- Try to clean up after BIST also in case test failed.
- `bar.m`, `barh.m`: Add plotting BISTs.
- Check if C and Fortran compilers accept `-fexceptions` flag.
  This affects building Octave itself from sources and also how .mex or .oct
  files are built by `mex` and `mkoctfile`.

Documentation

- Describe shape of outputs for `hist`.
- Simplify programming notes for `patch` objects.
- `vecnorm.m`: Add missing parenthesis to equation in docstring.
- Add example to Minimizers section on using anonymous functions to pass
  additional arguments to functions called by minimizer functions
  (`fminsearch`, `fminbnd`, `fminunc`).
- Add application notes in `fminsearch`, `fminbnd`, `fminunc` indicating the
  preferred way to pass parameters is through anonymous functions.
- Update remaining copyright statements to 2024.
- Minor fix for `setappdata.m`.
- Section "Assignment Expressions": Use `@emph` rather than `@i` macro for
  better rendering in plaintext formats.
- Section "Running Octave": Tell new users how to start Octave on their
  computers.
- `tsearch`: Add programming note about expected performance.

Deprecated functions, properties, and operators

- `fminsearch` parameter passing:  A legacy, undocumented, and only partially
  supported syntax for passing parameters to the minimized function `fcn`
  called by `fminsearch` by appending them to the input argument list has
  functioned intermittently since Octave 4.4.0.  Due to conflicts with other
  compatibility-required input methods the documentation of this syntax was
  removed in Octave 5.1.0, and the remaining functionality will be completely
  removed in Octave 10.  The preferred method of passing parameters to any of
  the minimization functions (including `fminsearch`, `fminbnd`, and `fminunc`)
  is through the use of anonymous functions.  Specific examples of this can be
  found in the "Minimizers" section of the GNU Octave manual.

Summary of important user-visible changes for version 8 (2023-03-07):
--------------------------------------------------------------------

### General improvements

- Octave's libraries are now built using symbol visibility by default.
  That means that fewer symbols are exported from these libraries.
  Configure with `--disable-lib-visibility-flags` to export all symbols
  (as in previous versions).

- `filter` is now 5X faster, which also speeds up `deconv`, `fftfilt`
  and `arma_rnd` by the same amount.

- `integral` can now return a second argument containing the error
  estimate from the underlying integrator.

- `perms` now accepts a second argument "unique" to return only unique
  permutations for inputs with repeated elements.  It is faster and
  takes less memory to call `perms ('aaaabbbbcccc', "unique")` than to
  call `unique (perms ('aaaabbbbcccc'), "rows")`.

- `quadgk` can now accept the `ArrayValued` input parameter to handle
  array-valued input functions.

- `delaunayn` now has consistent trivial simplex checking and removal
  for all input dimensions, simplex checking 3D inputs is now
  vectorized, and >3D simplex checking performance has been improved.
  Simplexes points are now ordered so they will all have positive
  outward normal vectors.  Input type checking has also been added for
  improved error handling.

- `factor` now factorizes all 64-bit integers in roughly the same time.
  Previously, the product of two large primes took much longer to factorize
  than highly composite inputs.

- `Refine` option is now implemented in functions `ode45`, `ode23`,
  and `ode23s`.

- Octave is now compatible with PCRE2 (UTF-8).  PCRE2 is preferred over PCRE
  if both are installed.  Configure with `--without-pcre2` if you prefer Octave
  to use PCRE in this case.

- `mean` now internally processes data as type double to reduce likelihood of
hitting overflow or precision limits with other types

### Graphical User Interface

- The GUI has a dark style and several new icons in toolbars for better
  visibility and higher contrast.

- A new terminal widget has been added for the GUI.  It is still experimental
  and is disabled by default.  It can be enabled with the command line
  parameter `--experimental-terminal-widget`.

- More fonts for the documentation browser are included.

### Graphics backend

- When printing, the option `-svgconvert` is now the default.  If you want to
use the more limited EPS-based tool chain (the former default)—e.g., if
you encounter inaccurate image rendering—you can pass the `-nosvgconvert`
option to the `print` function.

- Additional properties have been added to the `figure` graphics object:
    * `"innerposition"` (equivalent to `"position"`)
    * `"windowstate"` (not yet implemented)

- Legend now features a new property `"itemhitfcn"`, allowing the
  execution of a callback function when a legend item is clicked.

### Matlab compatibility

- `inline` functions now support all Matlab methods.  The performance
  of `inline` functions has also been improved.

- `sub2ind` now supports index values outside of the size specified by
  the subscripts.

- `cylinder` now accepts a scalar for the radius argument.

- `clock` now has an optional second output `ISDST` which indicates if
  Daylight Savings Time is in effect for the system's time zone.

- `print` now accepts option `-image` to specify the "opengl" renderer
  and `-vector` to specify the "painters" renderer.

- `format` now accepts the option "default", which is equivalent to
  calling `format` without any options to reset the default state.

- `quadgk` now stops iterating when `error <= tolerance` while the previous
  condition was `error < tolerance`.

- `mean` now accepts vector dimensions and options to handle `NaN` values.
  The option `"a"` (arithmetic mean), `"g"` (geometric mean), and `"h"`
  (harmonic mean) are no longer accepted, only the arithmetic mean is computed.
  For the geometric and harmonic mean, please use respective functions
  `geomean` and `harmmean` from the Octave Statistics package.

- `var` and `std` now optionally output a second argument containing the mean
  or weighted mean.

- `integral` can now accept the 'ArrayValued' option in combination with
  'RelTol' and 'WayPoints'.

- File system operations that remove files (e.g., `unlink` or `rmdir`) now also
  remove files that have their read-only file attribute set on Windows.

- The default state for certain graphics properties has been made
  consistent with Matlab.

        Object      | Property         | Default State
        ------------|------------------|------------
        figure      | "dockcontrols"   | "on"

- `ode45`, `ode23`, and `ode23s` have improved results for options `Events`,
  `OutputFcn`, and `Refine`, along with corrected orientation of struct
  outputs.

- *Early notice of future breaking changes*:  Due to many user requests that
  Octave should have a Matlab-compatible string class, there is work under way
  to implement a string class that will differ from a vector of characters.  In
  Octave, single-quoted character arrays are currently compatible with Matlab,
  but double-quoted forms are not.  Currently in Octave, both 'foo' and "foo"
  are largely interchangeable, barring certain escape sequence interpretations
  such as "\n" (converted to a single newline character) as opposed to '\n'
  (two separate characters).  Matlab’s single-quoted character arrays and
  double-quoted strings do not process backslash escape sequences, unlike many
  other languages, and those escape sequences are instead processed by
  individual functions such as `fprintf`.

  Octave's behavior is likely to change in future as a consequence of
  implementing Matlab-style string syntax.  For example, 'foo' will remain a
  three-element character vector, but "foo" will become a single-element string
  object.  Some backslash escape sequences are likely to differ from their
  current Octave behavior, but will achieve greater Matlab compatibility.  The
  exact implementation is a work in progress, and may or may not include
  methods of preserving backward compatibility.

  *What this means for user code*: If your code currently relies on
  double-quoted strings (e.g., "foo") representing character vectors as
  opposed to string objects, and if you intend to update to a future version of
  Octave incorporating the above changes, then consider replacing all
  double-quoted strings with single-quoted strings in your code over time
  (e.g., replace "foo" with 'foo'). Single-quoted strings are expected to
  retain current behavior.  Further, if your code relies on backslash escape
  sequence interpretation in double-quoted strings (except for special cases
  like the `printf` family), that code may need to change as well.

### Alphabetical list of new functions added in Octave 8

* `clearAllMemoizedCaches`
* `matlab.lang.MemoizedFunction`
* `memoize`
* `normalize`
* `pagectranspose`
* `pagetranspose`
* `uifigure`

### Deprecated functions, properties, and operators

The following functions and properties have been deprecated in Octave 8
and will be removed from Octave 10 (or whatever version is the second
major release after 8):

- Functions

        Function               | Replacement
        -----------------------|------------------
        shift                  | circshift
        sparse_auto_mutate     | none (see below)

- The `sparse_auto_mutate` function no longer has any effect on Octave's
  behavior.  Previously, after calling `sparse_auto_mutate (true)`,
  Octave would automatically convert sparse matrices to full when a
  sparse matrix required more memory than simply using full matrix
  storage.  This setting was `false` by default for compatibility with
  Matlab.  Now you must manually convert to full storage when desired.

- Properties

  The following property names are discouraged, but there is no fixed
  date for their removal.

        Object           | Property    | Replacement
        -----------------|-------------|------------
        uimenu           | label       | text
        uimenu           | callback    | menuselectedfcn

The following functions were deprecated in Octave 6 and have been removed
from Octave 8.

- Functions

        Function     | Replacement
        -------------|------------
        runtests     | oruntests

- The environment variable used by `mkoctfile` for linker flags is now
  `LDFLAGS` rather than `LFLAGS`.  `LFLAGS` was deprecated in Octave 6,
  and will be removed in a future version of Octave.

Summary of bugs fixed for version 8.1.0 (2023-01-22):
----------------------------------------------------

- Improved input validation and/or output handling for `poly`, `pinv`, `patch`,
  `fill`, `fill3`, `qp`, `datevec`, `textscan`, `sub2ind`, `qr`, `airy`,
  `regexp`, `dec2bin`, `dec2hex`, `mean`, and many others.
- Improved performance for `complex`, `fftw`, `delaunayn`, `isfield`, `tsearch`,
  sparse matrix exponentiation, other sparse operations, and many others.
- Overhauled `@audiorecorder` and `@audioplayer` classes.

actually used.
Change the PLIST so that -gnu is not used
references in patch-m4_acinclude.m4 mentions this.
Explicitly don't generate any docs since
generation octave.pdf breaks and it already exists.
Install info and man pages manually since they are
not installed due to docs not being generated.
Bump pkgrevision due to PLIST change.

octave: udpate to 6.2.0

This updates octave and also gets some more recommened dependencies in,
namely qrupdate and Mesalib (for osmesa) and gl2ps as well as the
qscintilla editor. The glpk option is on by default again.

This version of octave comes rather close to a standard build, with
optimzied BLAS and GUI fluff. We are still missing SuiteSparse and
SUNDIALS solvers, see

  https://octave.org/doc/v6.2.0/External-Packages.html

PortAudio should also be considered, and LLVM be watched if that
experimental JIT settles in.

Upstream changes since 5.x:

Summary of important user-visible changes for version 6.1.0 (2020-11-26):
------------------------------------------------------------------------

### General improvements

- The `intersect`, `setdiff`, `setxor`, `union`, and `unique` functions
  accept a new sorting option `"stable"` which will return output values
  in the same order as the input, rather than in ascending order.

- Complex RESTful web services can now be accessed by the `webread` and
  `webwrite` functions alongside with the `weboptions` structure.  One
  major feature is the support for cookies to enable RESTful
  communication with the web service.

  Additionally, the system web browser can be opened by the `web`
  function.

- The `linspace` function now produces symmetrical sequences when the
  endpoints are symmetric.  This is more intuitive and also compatible
  with recent changes made in Matlab R2019b.

- The underlying algorithm of the `rand` function has been changed.
  For single precision outputs, the algorithm has been fixed so that it
  produces values strictly in the range (0, 1).  Previously, it could
  occasionally generate the right endpoint value of 1 (See bug #41742).
  In addition, the new implementation uses a uniform interval between
  floating point values in the range (0, 1) rather than targeting a
  uniform density (# of random integers / length along real number
  line).

- Numerical integration has been improved.  The `quadv` function has
  been re-written so that it can compute integrands of periodic
  functions.  At the same time, performance is better with ~3.5X fewer
  function evaluations required.  A bug in `quadgk` that caused complex
  path integrals specified with `"Waypoints"` to occasionally be
  calculated in the opposite direction was fixed.

- The `edit` function option `"editinplace"` now defaults to `true` and
  the option `"home"` now defaults to the empty matrix `[]`.  Files will
  no longer be copied to the user's HOME directory for editing.  The old
  behavior can be restored by setting `"editinplace"` to `false` and
  `"home"` to `"~/octave"`.

- The `format` command supports two new options: `uppercase` and
  `lowercase` (default).  With the default, print a lowercase 'e' for
  the exponent character in scientific notation and lowercase 'a-f' for
  the hex digits representing 10-15.  With `uppercase`, print 'E' and
  'A-F' instead.  The previous uppercase formats, `E` and `G`, no longer
  control the case of the output.

  Additionally, the `format` command can be called with multiple options
  for controlling the format, spacing, and case in arbitrary order.
  For example:

        format long e uppercase loose

  Note, in the case of multiple competing format options the rightmost
  one is used, and, in case of an error, the previous format remains
  unchanged.

- L-value references (e.g., increment (++), decrement (--), and all
  in-place assignment operators (+=, -=, *=, /=, etc.)) are no longer
  allowed in anonymous functions.

- New warnings have been added about questionable uses of the colon ':'
  range operator.  Each has a new warning ID so that it can be disabled
  if desired.

  >  `Octave:colon-complex-argument`   : when any arg is complex
  >  `Octave:colon-nonscalar-argument` : when any arg is non-scalar

- The `regexp` and related functions now correctly handle and *require*
  strings in UTF-8 encoding.  As with any other function that requires
  strings to be encoded in Octave's native encoding, you can use
  `native2unicode` to convert from your preferred locale.  For example,
  the copyright symbol in UTF-8 is `native2unicode (169, "latin1")`.

- The startup file `octaverc` can now be located in the platform
  dependent location for user local configuration files (e.g.,
  ${XDG_CONFIG_HOME}/octave/octaverc on Unix-like operating systems or
  %APPDATA%\octave\octaverc on Windows).

- `pkg describe` now lists dependencies and inverse dependencies
  (i.e., other installed packages that depend on the package in
  question).

- `pkg test` now tests all functions in a package.

- When unloading a package, `pkg` now checks if any remaining loaded
  packages depend on the one to be removed.  If this is the case `pkg`
  aborts with an explanatory error message.  This behavior can be
  overridden with the `-nodeps` option.

- The command

    dbstop in CLASS at METHOD

  now works to set breakpoints in classdef constructors and methods.

#### Graphics backend

- The use of Qt4 for graphics and the GUI is deprecated in Octave
  version 6 and no further bug fixes will be made.  Qt4 support will be
  removed completely in Octave version 7.

- The `legend` function has been entirely rewritten.  This fixes a
  number of historical bugs, and also implements new properties such as
  `"AutoUpdate"` and `"NumColumns"`.  The gnuplot toolkit---which is no
  longer actively maintained---still uses the old legend function.

- The `axis` function was updated which resolved 10 bugs affecting
  axes to which `"equal"` had been applied.

- Graphic primitives now accept a color property value of `"none"`
  which is useful when a particular primitive needs to be hidden
  (for example, the Y-axis of an axes object with `"ycolor" = "none"`)
  without hiding the entire primitive `"visibility" = "off"`.

- A new property `"FontSmoothing"` has been added to text and axes
  objects that controls whether anti-aliasing is used during the
  rendering of characters.  The default is `"on"` which produces smooth,
  more visually appealing text.

- The figure property `"windowscrollwheelfcn"`is now implemented.
  This makes it possible to provide a callback function to be executed
  when users manipulate the mouse wheel on a given figure.

- The figure properties `"pointer"`, `"pointershapecdata"`, and
  `"pointershapehotspot"` are now implemented.  This makes it possible
  to change the shape of the cursor (pointer in Matlab-speak) displayed
  in a plot window.

- The figure property `"paperpositionmode"` now has the default `"auto"`
  rather than `"manual"`.  This change is more intuitive and is
  Matlab compatible.

- The appearance of patterned lines `"LineStyle" = ":"|"--"|"-."` has
  been improved for small widths (`"LineWidth"` less than 1.5 pixels)
  which is a common scenario.

- Printing to EPS files now uses a tight bounding box (`"-tight"`
  argument to print) by default.  This makes more sense for EPS
  files which are normally embedded within other documents, and is
  Matlab compatible.  If necessary use the `"-loose"` option to
  reproduce figures as they appeared in previous versions of Octave.

- The following print devices are no longer officially supported: cdr,
  corel, aifm, ill, cgm, hpgl, mf and dxf.  A warning will be thrown
  when using those devices, and the code for supporting those formats
  will eventually be removed from a future version of Octave.

- The placement of text subscripts and superscripts has been
  re-engineered and now produces visually attractive results similar to
  Latex.

### Matlab compatibility

- The function `unique` now returns column index vectors for the second
  and third outputs.  When duplicate values are present, the default
  index to return is now the `"first"` occurrence.  The previous Octave
  behavior, or Matlab behavior from releases prior to R2012b, can be
  obtained by using the `"legacy"` flag.

- The function `setdiff` with the `"rows"` argument now returns Matlab
  compatible results.  The previous Octave behavior, or Matlab behavior
  from releases prior to R2012b, can be obtained by using the `"legacy"`
  flag.

- The functions `intersect`, `setxor`, and `union` now accept a
  `"legacy"` flag which changes the index values (second and third
  outputs) as well as the orientation of all outputs to match Matlab
  releases prior to R2012b.

- The function `streamtube` is Matlab compatible and plots tubes along
  streamlines which are scaled by the vector field divergence. The
  Octave-only extension `ostreamtube` can be used to visualize the flow
  expansion and contraction of the vector field due to the local
  crossflow divergence.

- The interpreter now supports handles to nested functions.

- The graphics properties `"LineWidth"` and `"MarkerSize"` are now
  measured in points, *not* pixels.  Compared to previous versions
  of Octave, some lines and markers will appear 4/3 larger.

- The meta.class property "SuperClassList" has been renamed
  "Superclasslist" for Matlab compatibility.  The original name will
  exist as an alias until Octave version 8.1.

- Inline functions created by the function `inline` are now of type
  "inline" when interrogated with the `class` function.  In previous
  versions of Octave, the class returned was "function_handle".  This
  change is Matlab compatible.  Inline functions are deprecated in
  both Matlab and Octave and support may eventually be removed.
  Anonymous functions can be used to replace all instances of inline
  functions.

- The function `javaaddpath` now prepends new directories to the
  existing dynamic classpath by default.  To append them instead, use
  the new `"-end"` argument.  Multiple directories may now be specified
  in a cell array of strings.

- An undocumented function `gui_mainfcn` has been added, for compatibility
  with figures created with Matlab's GUIDE.

- Several validator functions of type `mustBe*` have been added.  See
  the list of new functions below.

math/octave: add missing header for use of exit system call

Update to 5.1.0

Changelog:
# General improvements

    The Octave plotting system now supports high resolution screens, i.e., those with greater than 96 DPI which are referred to as HiDPI/Retina monitors.

    Unicode character support for files and folders in Windows.

    A new core function movfun will apply a function to a sliding window of arbitrary size on a dataset and accumulate the results. Many common cases have been implemented using the naming scheme movXXX where XXX is the function that will be applied. For example, the moving average over a dataset is movmean. New moving window functions:

    movfun movslice movmad movmax movmean movmedian movmin movprod movstd movsum movvar

    The fsolve function has been tweaked to use larger step sizes when calculating the Jacobian of a function with finite differences. This leads to faster convergence.

    The ranks function has been recoded for performance and is now 25X faster. In addition, it now supports a third argument that specifies how to resolve the ranking of tie values.

    The function randi has been recoded to produce an unbiased (all results are equally likely) sample of integers. This may produce different results in existing code. If it is necessary to reproduce the exact random integer sequence as in previous versions use

    ri = imin + floor ((imax - imin + 1) * rand ());

    The function isdefinite now returns true or false rather than -1, 0, or 1. To test for a positive semi-definite matrix (old output of 0) check whether the following two conditions hold:

    isdefinite (A) => 0 and isdefinite (A + 5*TOL, TOL) => 1

    The intmax, intmin, and flintmax functions now accept a variable as input. Existing code to query the range of an existing variable can be simplified by removing the call to class that was previously required. For example defining the variable x = int8 (3) in the workspace, calls like

    range = [ intmin(class(x)), intmax(class(x)) ]

    can in Octave 5 be simplified to range = [ intmin(x), intmax(x) ].

    The path handling functions no longer perform variable or brace expansion on path elements and Octave’s load-path is no longer subject to these expansions.

    A new printing device is available, "-ddumb", which produces ASCII art for plots. This device is only available with the gnuplot toolkit.

# Dependencies

    The GUI requires Qt libraries. The minimum Qt4 version supported is Qt4.8. Qt5 of any version is preferred.

    The OSMesa library is no longer used. To print invisible figures when using OpenGL graphics, the Qt QOFFSCREENSURFACE feature must be available and you must use the qt graphics toolkit.

    The FFTW library is now required to perform FFT calculations. The FFTPACK sources have been removed from Octave.

Matlab compatibility
* Many improvements.

octave: fix building with recent Qt5

Do not look for qcollectiongenerator, it has been incorporared into qhelpgenerator.

Octave: update to 4.4.1

Remove hack that had a high chance of resulting in a dysfunctional package
qttools can't be a build dependency because we link against something
in it.

XXX pkgsrc claims this package has work directory references

Summary of important user-visible changes for version 4.4 (2018-04-30):
----------------------------------------------------------------------

 ** A graphical Variable Editor has been added to the GUI interface.
    It uses a spreadsheet-like interface for quick, intuitive editing
    of variables.  The Variable Editor is launched by double-clicking
    on a variable name in the Workspace Window or by typing
    "openvar VARIABLE_NAME" in the Command Window.

 ** On systems with 64-bit pointers, --enable-64 is now the default and
    Octave always uses 64-bit indexing.  However, if the configure
    script determines that the BLAS library uses 32-bit integers, then
    operations using the following libraries are limited to arrays with
    dimensions that are smaller than 2^31 elements:

      BLAS  LAPACK  QRUPDATE  SuiteSparse  ARPACK

    Additionally, the following libraries use "int" internally, so
    maximum problem sizes are always limited:

      glpk  Qhull

 ** The octave command no longer starts the GUI by default.  Most users
    starting Octave from a shell were expecting the command line
    interface, and desktop launchers already required the `--force-gui'
    option.  With this change, desktop launchers should be modified to
    use the new option `--gui'.  The previous `--force-gui' option will
    continue to work, and maps to `--gui', but it will be removed in
    Octave 6.

 ** A known bug in Qt (https://bugreports.qt.io/browse/QTBUG-55357) is
    addressed by limiting GUI sub-panel relocation capabilities for Qt
    versions in the range >= 5.6.1 and < 5.7.1.  However, this may not
    thoroughly avoid issues on all platforms.

 ** A new container data type--containers.Map--is available.  Map is a
    key/value storage container (a.k.a, a hash) that efficiently allows
    storing and retrieving values by name, rather than by position which
    is how arrays work.

 ** The bareword "import" is now recognized in scripts and functions.
    However, the functionality to import functions and classes from
    other namespaces into the local scope has not yet been implemented.
    Attempting to use "import" will provoke an error message.

 ** hex2num and num2hex now work for integer and char types and num2hex
    may optionally return a cell array of strings instead of a character
    array.  If given a cell array of strings, hex2num now returns a
    numeric array of the same size as the input cell array.  Previously,
    hex2num would accept a cell array of strings of arbitrary dimension
    but would always return a column vector.

 ** New special functions cosint, sinint, and gammaincinv have been added.

 ** Special functions in Octave have been rewritten for larger input
    domains, better accuracy, and additional options.
    * gammainc now accepts negative real values for X.
    * improved accuracy for gammainc, betainc, betaincinv, expint.
    * gammainc has new options "scaledlower" and "scaledupper".
    * betainc, betaincinv have new option "upper".

 ** The "names" option used in regular expressions now returns a struct
    array, rather than a struct with a cell array for each field.  This
    change was made for Matlab compatibility.

 ** The quadcc function now uses both absolute tolerance and relative
    tolerance to determine the stopping criteria for an integration.
    To be compatible with other quadXXX functions, such as quadgk, the
    calling syntax has changed to

      quadcc (f, a, b, [AbsTol, [RelTol]])

    To update existing code, change instances of RelTol to [0, RelTol].

      quadcc (f, a, b, tol) => quadcc (f, a, b, [0, tol])

    A warning that a single tolerance input is now interpreted as an
    absolute tolerance will be issued in Octave versions 4.4 and 5,
    after which it will be removed.  The warning has ID
    "Octave:quadcc:RelTol-conversion" and can be disabled with

      warning ("off", "Octave:quadcc:RelTol-conversion")

 ** The qr function now returns a standard factorization unless
    explicitly instructed to perform an economy factorization by using a
    final argument of 0.

 ** The Qt graphics toolkit now supports offscreen printing without osmesa
    if Octave was built with Qt >= 5.1.

 ** The built-in pager for display of large data is now disabled by
    default.  To re-enable it for every Octave session add the following
    to your .octaverc file:

      more on;

 ** The FLTK toolkit is no longer prioritized for development.  The
    number of Octave Maintainers is too small to support three different
    graphic toolkits.  New development will target the Qt toolkit.
    While no longer prioritized, the FLTK toolkit is not deprecated and
    there is no schedule for its removal.

 ** The graphic object property "PickableParts" has been implemented
    which controls whether an object can accept mouse clicks.

 ** The graphic object property "Interruptible" has been fully
    implemented which controls whether a running callback function can
    be interrupted by another callback function.

 ** The graphic object property "HitTest" has been updated to be fully
    compatible with Matlab.

 ** Text objects now implement the properties "BackgroundColor",
    "EdgeColor", "LineStyle", "LineWidth", and "Margin".

 ** An initial implementation of alpha transparency has been made for
    patch and surface objects.  Printing to svg and pdf is supported.

 ** ishandle now returns true for both graphics handle objects and
    Java objects.  The latter change was made for Matlab compatibility.
    Use ishghandle or isgraphics if it is important not to include Java
    objects.

 ** The pkg command now accepts a URL as an argument, allowing a valid
    Octave package to be installed from any remote host with one command,
    for example

      pkg install https://example.org/download/example-package.tar.gz

 ** The following statistical functions have been moved from core
    Octave to the statistics package available from Octave Forge.

    The following properties or allowed corresponding values have been
    deprecated in Octave 4.4 and will be removed from Octave 6 (or whatever
    version is the second major release after 4.4):

 ** The rectangle and ellipse annotation property "edgecolor" has been
    deprecated and will be removed from Octave 6 (or whatever version
    is the second major release after 4.4).  Use the property "color"
    instead.

octave: amend wrapper patches to be netbsd-specific. fix sunOS build

octave is using gnulib for portability, but has an additional wrapper
around it. unfortunately that means that this type signature is no longer
portable. netbsd doesn't have struct tm_zone, others do.

I failed to use gnulib to provide struct tm_zone, using an OS-specific macro
as an ugly hack.

Octave: update to 4.2.0

pkgsrc changes: removed all patches to do with qt5 support, upstream
code does it now. blindly moved some patches that were replacing
INSTALL_PROGRAM to INSTALL_LIB as the build changed. added patch
replacing struct tm_zone with timezone_t to accommodate for missing
type in NetBSD - same as libgnu does.

ok adam

Summary of important user-visible changes for version 4.2:
---------------------------------------------------------

 ** The parser has been extended to accept, but ignore, underscore
    characters in numbers.  This facilitates writing more legible code
    by using '_' as a thousands separator or to group nibbles into bytes
    in hex constants.

    Examples: 1_000_000 == 1e6  or  0xDE_AD_BE_EF

 ** The parser has been extended to understand binary numbers which
    begin with the prefix '0b' or '0B'.  The value returned is Octave's
    default numeric class of double, not at unsigned integer class.
    Therefore numbers greater than flintmax, i.e., 2^53, will lose some
    precision.

    Examples: 0b101 == 5  or  0B1100_0001 == 0xC1

 ** gnuplot 4.4 is now the minimum version supported by Octave.

 ** The default set of colors used to plot lines has been updated to be
    compatible with Matlab's new default color scheme.  The line plot
    color scheme can be set with the axes property "ColorOrder".

 ** The default colormap is now set to "viridis" which is also the
    default colormap in matplotlib.  This new colormap fixes some of the
    main issues with the old default colormap "jet" such as its bad
    "luminance profile" and is also more similar to Matlab's new default
    colormap "parula".

 ** The colormap function no longer supports the input argument "list"
    to show built-in colormaps.  Use "help colormap" to find the
    built-in colormaps.

 ** The graphics command "hold on" now ensures that each new plot added
    to an existing plot has a different color or linestyle according to
    the "ColorOrder" and/or "LineStyleOrder" properties.  This is
    equivalent to the old command "hold all" and was made for Matlab
    compatibility.  Existing code *may* produce differently colored
    plots if it did not specify the color for a plot and relied on each
    new plot having the default first color in the "ColorOrder"
    property.

 ** When starting, Octave now looks in the function path for a file
    startup.m and executes any commands found there.  This change was
    made to accommodate Matlab users.  Octave has it's own configuration
    system based on the file .octaverc which is preferred.

 ** Octal ('\NNN') and hex ('\xNN') escape sequences in single quoted
    strings are now interpreted by the function do_string_escapes().
    The *printf family of functions now supports octal and hex escape
    sequences in single-quoted strings for Matlab compatibility.

 ** Special octal and hex escape sequences for the pattern and
    replacement strings in regular expressions are now interpreted for
    Matlab compatibility.

    octal: '\oNNN' or '\o{NNN}'
    hex  : '\xNN'  or '\x{NN}'

 ** Unknown escape sequences in the replacement string for regexprep are
    now substituted with their unescaped version and no warning is
    emitted.  This change was made for Matlab compatibility.

    Example: regexprep ('a', 'a', 'x\yz')
             => 'xyz'

 ** mkfifo now interprets the MODE argument as an octal, not decimal,
    integer.  This is consistent with the equivalent shell command.

 ** linspace now returns an empty matrix if the number of requested
    points is 0 or a negative number.  This change was made to be
    compatible with Matlab releases newer than 2011.  In addition,
    Octave no longer supports matrix inputs for A or B.

 ** The cov function now returns the complex conjugate of the result
    from previous versions of Octave.  This change was made for
    compatibility with Matlab.

 ** condest now works with a normest1 compatible syntax.

 ** The griddata function no longer plots the interpolated mesh if no
    output argument is requested, instead the vector or array of
    interpolated values is always returned for Matlab compatibility.

 ** The new function "light" and the corresponding graphics object
    provide light and shadow effects for patch and surface objects.

 ** The surfnorm function now returns unnormalized (magnitude != 1)
    normal vectors for compatibility with Matlab.

 ** The normal vectors returned from isonormals have been reversed to
    point towards smaller values for compatibility with Matlab.

 ** The quadl function now uses an absolute, rather than relative,
    tolerance for Matlab compatibility.  The default tolerance is 1e-6
    which may result in lower precision results than previous versions
    of Octave which used eps as the relative tolerance.  The quadl
    function has also been extended to return a second output with the
    total number of function evaluations.

 ** The textscan function is now built-in and is much faster and much
    more Matlab-compatible than the previous m-file version.

 ** Dialog boxes--errordlg, helpdlg, inputdlg, listdlg, msgbox,
    questdlg, and warndlg--now exclusively use Qt for rendering.
    Java based versions have been removed.

 ** The axes properties "TitleFontSizeMultiplier" and "TitleFontWeight"
    are now implemented which control the default appearance of text
    created with title().
    The axes property "LabelFontSizeMultiplier" is now implemented
    which controls the default appearance of text created with
    xlabel(), ylabel(), or zlabel().

 ** The graphics property "box" for axes now defaults to "off".
    To obtain equivalent plots to previous versions of Octave use
      set (0, "DefaultAxesBox", "on");
    in your .octaverc file.

 ** The graphics property "boxstyle" has been implemented.  The default
    is "back" which draws only the back planes in a 3-D view.  If the
    option is "full" then all planes are drawn.

 ** The graphics property "erasemode" has been hidden, and will
    eventually be removed.  This property has also been removed
    from Matlab, and was never implemented in Octave.

 ** The graphics property "graphicssmoothing" for figures now controls
    whether anti-aliasing will be used for lines.  The default is "on".

 ** The value "zero" for the axes properties "xaxislocation" and
    "yaxislocation" has been deprecated and will be removed from
    Octave 4.6.  Use "origin" instead.

 ** The publish function allows easy publication of Octave script files
    in HTML or other formats, including figures and output created by
    this script.  It comes with its counterpart grabcode, which lets one
    literally grab the HTML published code from a remote website, for
    example.

 ** The value of the MEX variable TrapFlag now defaults to 0, which will
    cause Octave to abort execution of a MEX file and return to the
    prompt if an error is encountered in mexCallMATLAB.

 ** The MEX API now includes the function mexCallMATLABWithTrap.  This
    function will not abort if an error occurs during mexCallMATLAB, but
    instead will return execution to the MEX function for error
    handling.

 ** The MEX API functions for input validation that begin with "mxIs"
    (e.g., mxIsDouble, mxIsEmpty, etc.) now return type bool rather than
    type int.

 ** The functions mxAssert and mxAssertS for checking assertions have
    been added.  In order to avoid a performance penalty they are only
    compiled in to debug versions of a MEX file, i.e., that are produced
    when the '-g' option is given to mex or mkoctfile.

 ** Other new MEX API functions include mexEvalStringWithTrap,
    mxIsScalar, mxCreateUninitNumericArray, mxCreateUninitNumericMatrix.

 ** Other new functions added in 4.2:

      audioformats
      camlight
      condeig

 ** Deprecated functions.

    The following functions have been deprecated in Octave 4.2 and will
    be removed from Octave 4.6 (or whatever version is the second major
    release after 4.2):

      Function             | Replacement
      ---------------------|------------------
      bitmax               | flintmax
      mahalanobis          | mahal in Octave-Forge statistics pkg
      md5sum               | hash
      octve_config_info    | __octave_config_info__
      onenormest           | normest1
      sleep                | pause
      usleep               | pause
      wavread              | audioread
      wavwrite             | audiowrite

 ** The following functions were deprecated in Octave 3.8 and have been
    removed from Octave 4.2.

      default_save_options    java_new
      gen_doc_cache           java_unsigned_conversion
      interp1q                javafields
      isequalwithequalnans    javamethods
      java_convert_matrix     re_read_readline_init_file
      java_debug              read_readline_init_file
      java_invoke             saving_history

 ** The global error_state variable in Octave's C++ API has been
    deprecated and will be removed in a future version.  Now the error
    and print_usage functions throw an exception
    (octave::execution_exception) after displaying the error message.
    This makes the error and print_usage functions in C++ work more like
    the corresponding functions in the scripting language.

 ** The default error handlers in liboctave have been updated to use
    exceptions.  After displaying an error message they no longer return
    control to the calling program.  The error handler function can be
    customized through the global variables
    "current_liboctave_error_handler" and
    "current_liboctave_error_with_id_handler".  If a programmer has
    installed their own custom error handling routines when directly
    linking with liboctave then these must be updated to throw an
    exception and not return to the calling program.

 ** The system for common errors and warnings has been renamed from
    gripe_XXX to either err_XXX if error is called or warn_XXX if
    warning is called.  The gripe_XXX functions are deprecated and will
    be removed in version 4.6.

 ** New configure option, --enable-address-sanitizer-flags, to build
    Octave with memory allocator checks (similar to those in valgrind)
    built in.

octave: fix linux install

we pass and assume a given MACHINE_GNU_PLATFORM, but this package did not
use this value due to an error.
the guess it had for linux (x86_64-unknown-linux-gnu) is different, and
this seems to trample over our own tools, see:
https://mail-index.netbsd.org/pkgsrc-users/2014/03/26/msg019464.html

add this patch to the original m4 script too, not just the resulting configure
file, so it won't be accidentially forgotten (and can be upstreamed).

Update to Octave 3.6.2


Summary of important user-visible changes for version 3.6:
---------------------------------------------------------

 ** The PCRE library is now required to build Octave.  If a pre-compiled
    package does not exist for your system, you can find PCRE sources
    at http://www.pcre.org

 ** The ARPACK library is no longer distributed with Octave.
    If you need the eigs or svds functions you must provide an
    external ARPACK through a package manager or by compiling it
    yourself.  If a pre-compiled package does not exist for your system,
    you can find the current ARPACK sources at
    http://forge.scilab.org/index.php/p/arpack-ng

 ** Many of Octave's binary operators (.*, .^, +, -, ...) now perform
    automatic broadcasting for array operations which allows you to use
    operator notation instead of calling bsxfun or expanding arrays (and
    unnecessarily wasting memory) with repmat or similar idioms.  For
    example, to scale the columns of a matrix by the elements of a row
    vector, you may now write

      rv .* M

    In this expression, the number of elements of rv must match the
    number of columns of M.  The following operators are affected:

      plus      +  .+
      minus     -  .-
      times     .*
      rdivide   ./
      ldivide   .\
      power     .^  .**
      lt        <
      le        <=
      eq        ==
      gt        >
      ge        >=
      ne        !=  ~=
      and       &
      or        |
      atan2
      hypot
      max
      min
      mod
      rem
      xor

    additionally, since the A op= B assignment operators are equivalent
    to A = A op B, the following operators are also affected:

      +=  -=  .+=  .-=  .*=  ./=  .\=  .^=  .**=  &=  |=

    See the "Broadcasting" section in the new "Vectorization and Faster
    Code Execution" chapter of the manual for more details.

 ** Octave now features a profiler, thanks to the work of Daniel Kraft
    under the Google Summer of Code mentorship program.  The manual has
    been updated to reflect this addition.  The new user-visible
    functions are profile, profshow, and profexplore.

 ** Overhaul of statistical distribution functions

    Functions now return "single" outputs for inputs of class "single".

    75% reduction in memory usage through use of logical indexing.

    Random sample functions now use the same syntax as rand and accept
    a comma separated list of dimensions or a dimension vector.

    Functions have been made Matlab-compatible with regard to special
    cases (probability on boundaries, probabilities for values outside
    distribution, etc.).  This may cause subtle changes to existing
    scripts.

    negative binomial function has been extended to real, non-integer
    inputs.  The discrete_inv function now returns v(1) for 0 instead of
    NaN.  The nbincdf function has been recoded to use a closed form
    solution with betainc.

 ** strread, textscan, and textread have been completely revamped.

    They now support nearly all Matlab functionality including:

      * Matlab-compatible whitespace and delimiter defaults

      * Matlab-compatible options: 'whitespace', treatasempty', format
        string repeat count, user-specified comment style, uneven-length
        output arrays, %n and %u conversion specifiers (provisionally)

 ** All .m string functions have been modified for better performance or
    greater Matlab compatibility.  Performance gains of 15X-30X have
    been demonstrated.  Operations on cell array of strings no longer pay
    quite as high a penalty as those on 2-D character arrays.

      deblank:  Now requires character or cellstr input.

      strtrim:  Now requires character or cellstr input.
                No longer trims nulls ("\0") from string for Matlab
                compatibility.

      strmatch: Follows documentation precisely and ignores trailing spaces
                in pattern and in string.  Note that this is documented
                Matlab behavior but the implementation apparently does
                not always follow it.

      substr:   Now possible to specify a negative LEN option which
                extracts to within LEN of the end of the string.

      strtok:   Now accepts cellstr input.

      base2dec, bin2dec, hex2dec:
                Now accept cellstr inputs.

      dec2base, dec2bin, dec2hex:
                Now accept cellstr inputs.

      index, rindex:
                Now accept 2-D character array input.

      strsplit: Now accepts 2-D character array input.

 ** Geometry functions derived from Qhull (convhull, delaunay, voronoi)
    have been revamped.  The options passed to the underlying qhull
    command have been changed for better results or for Matlab
    compatibility.

      convhull: Default options are "Qt" for 2D, 3D, 4D inputs
                Default options are "Qt Qx" for 5D and higher

      delaunay: Default options are "Qt Qbb Qc Qz" for 2D and 3D inputs
                Default options are "Qt Qbb Qc Qx" for 4D and higher

      voronoi:  No default arguments

 ** Date/Time functions updated.  Millisecond support with FFF format
    string now supported.

    datestr: Numerical formats 21, 22, 29 changed to match Matlab.
             Now accepts cellstr input.

 ** The following warning IDs have been removed:

      Octave:associativity-change
      Octave:complex-cmp-ops
      Octave:empty-list-elements
      Octave:fortran-indexing
      Octave:precedence-change

 ** The warning ID Octave:string-concat has been renamed to
    Octave:mixed-string-concat.

 ** Octave now includes the following Matlab-compatible preference
    functions:

      addpref  getpref  ispref  rmpref  setpref

 ** The following Matlab-compatible handle graphics functions have been
    added:

      guidata         uipanel        uitoolbar
      guihandles      uipushtool     uiwait
      uicontextmenu   uiresume       waitfor
      uicontrol       uitoggletool

    The uiXXX functions above are experimental.

    Except for uiwait and uiresume, the uiXXX functions are not
    supported with the FLTK+OpenGL graphics toolkit.

    The gnuplot graphics toolkit does not support any of the uiXXX
    functions nor the waitfor function.

 ** New keyword parfor (parallel for loop) is now recognized as a valid
    keyword.  Implementation, however, is still mapped to an ordinary
    for loop.

 ** Other new functions added in 3.6.0:

      bicg                       nthargout                   usejava
      is_dq_string               narginchk                   waitbar
      is_sq_string               python                      zscore
      is_function_handle         register_graphics_toolkit
      loaded_graphics_toolkits   recycle

 ** Deprecated functions.

    The following functions were deprecated in Octave 3.2 and have been
    removed from Octave 3.6.

      create_set          spcholinv    splu
      dmult               spcumprod    spmax
      iscommand           spcumsum     spmin
      israwcommand        spdet        spprod
      lchol               spdiag       spqr
      loadimage           spfind       spsum
      mark_as_command     sphcat       spsumsq
      mark_as_rawcommand  spinv        spvcat
      spatan2             spkron       str2mat
      spchol              splchol      unmark_command
      spchol2inv          split        unmark_rawcommand

    The following functions have been deprecated in Octave 3.6 and will
    be removed from Octave 3.10 (or whatever version is the second major
    release after 3.6):

      cut                is_duplicate_entry
      cor                polyderiv
      corrcoef           shell_cmd
      __error_text__     studentize
      error_text         sylvester_matrix

 ** The following functions have been modified for Matlab compatibility:

      randperm

Fix the bloody fpos_t/off_t mess.

Update to Octave 3.4.3
This makes the package build and work at least in NetBSD on some platforms.


Summary of important user-visible changes for version 3.4.3:
-----------------------------------------------------------

 ** Octave 3.4.3 is a bug fixing release.

Summary of important user-visible changes for version 3.4.2:
-----------------------------------------------------------

 ** Octave 3.2.4 fixes some minor installation problems that affected
    version 3.4.1.

Summary of important user-visible changes for version 3.4.1:
-----------------------------------------------------------

 ** Octave 3.4.1 is primarily a bug fixing release.

 ** IMPORTANT note about binary incompatibility in this release:

    Binary compatibility for all 3.4.x releases was originally planned,
    but this is impossible for the 3.4.1 release due to a bug in the way
    shared libraries were built in Octave 3.4.0.  Because of this bug,
    .oct files built for Octave 3.4.0 must be recompiled before they
    will work with Octave 3.4.1.

    Given that there would be binary incompatibilities with shared
    libraries going from Octave 3.4.0 to 3.4.1, the following
    incompatible changes were also made in this release:

      * The Perl Compatible Regular Expression (PCRE) library is now
        required to build Octave.

      * Octave's libraries and .oct files are now installed in
        subdirectories of $libdir instead of $libexecdir.

    Any future Octave 3.4.x release versions should remain binary
    compatible with Octave 3.4.1 as proper library versioning is now
    being used as recommended by the libtool manual.

 ** The following functions have been deprecated in Octave 3.4.1 and will
    be removed from Octave 3.8 (or whatever version is the second major
    release after 3.4):

      cquad  is_duplicate_entry  perror  strerror

 ** The following functions are new in 3.4.1:

      colstyle  gmres  iscolumn  isrow  mgorth  nproc  rectangle

 ** The get_forge_pkg function is now private.

 ** The rectangle_lw, rectangle_sw, triangle_lw, and triangle_sw
    functions are now private.

 ** The logistic_regression_derivatives and logistic_regression_likelihood
    functions are now private.

 ** ChangeLog files in the Octave sources are no longer maintained
    by hand.  Instead, there is a single ChangeLog file generated from
    the Mercurial version control commit messages.  Older ChangeLog
    information can be found in the etc/OLD-ChangeLogs directory in the
    source distribution.

Summary of important user-visible changes for version 3.4:
---------------------------------------------------------

 ** BLAS and LAPACK libraries are now required to build Octave.  The
    subset of the reference BLAS and LAPACK libraries has been removed
    from the Octave sources.

 ** The `lookup' function was extended to be more useful for
    general-purpose binary searching.  Using this improvement, the
    ismember function was rewritten for significantly better
    performance.

 ** Real, integer and logical matrices, when used in indexing, will now
    cache the internal index_vector value (zero-based indices) when
    successfully used as indices, eliminating the conversion penalty for
    subsequent indexing by the same matrix.  In particular, this means it
    is no longer needed to avoid repeated indexing by logical arrays
    using find for performance reasons.

 ** Logical matrices are now treated more efficiently when used as
    indices.  Octave will keep the index as a logical mask unless the
    ratio of true elements is small enough, using a specialized
    code.  Previously, all logical matrices were always first converted
    to index vectors.  This results in savings in both memory and
    computing time.

 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled
    functions for better performance.  These functions are now faster,
    can deliver more economized results for ranges, and can reuse the
    index cache mechanism described in previous paragraph.

 ** The built-in function equivalents to associative operators (`plus',
    `times', `mtimes', `and', and `or') have been extended to accept
    multiple arguments.  This is especially useful for summing
    (multiplying, etc.) lists of objects (of possibly distinct types):

      matrix_sum = plus (matrix_list{:});

 ** An FTP object type based on libcurl has been implemented.  These
    objects allow ftp connections, downloads and uploads to be
    managed.  For example,

      fp = ftp ("ftp.octave.org);
      cd (fp, "gnu/octave");
      mget (fp, "octave-3.2.3.tar.bz2");
      close (fp);

 ** The default behavior of `assert (observed, expected)' has been
    relaxed to employ less strict checking that does not require the
    internals of the values to match.  This avoids previously valid
    tests from breaking due to new internal classes introduced in future
    Octave versions.

    For instance, all of these assertions were true in Octave 3.0.x
    but false in 3.2.x due to new optimizations and improvements:

      assert (2*linspace (1, 5, 5), 2*(1:5))
      assert (zeros (0, 0), [])
      assert (2*ones (1, 5), (2) (ones (1,5)))

 ** The behavior of library functions `ismatrix', `issquare', and
    `issymmetric' has been changed for better consistency.

    * The `ismatrix' function now returns true for all numeric,
      logical and character 2-D or N-D matrices.  Previously, `ismatrix'
      returned false if the first or second dimension was zero.
      Hence, `ismatrix ([])' was false,
      while `ismatrix (zeros (1,2,0))' was true.

    * The `issquare' function now returns a logical scalar, and is
      equivalent to the expression

        ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x)

      The dimension is no longer returned.  As a result, `issquare ([])'
      now yields true.

    * The `issymmetric' function now checks for symmetry instead of
      Hermitianness.  For the latter, ishermitian was created.  Also,
      logical scalar is returned rather than the dimension, so
      `issymmetric ([])' is now true.

 ** Function handles are now aware of overloaded functions.  If a
    function is overloaded, the handle determines at the time of its
    reference which function to call.  A non-overloaded version does not
    need to exist.

 ** Overloading functions for built-in classes (double, int8, cell,
    etc.) is now compatible with Matlab.

 ** Function handles can now be compared with the == and != operators,
    as well as the `isequal' function.

 ** Performance of concatenation (using []) and the functions `cat',
    `horzcat', and `vertcat' has been improved for multidimensional
    arrays.

 ** The operation-assignment operators +=, -=, *= and /= now behave more
    efficiently in certain cases.  For instance, if M is a matrix and S a
    scalar, then the statement

      M += S;

    will operate on M's data in-place if it is not shared by another
    variable, usually increasing both time and memory efficiency.

    Only selected common combinations are affected, namely:

      matrix += matrix
      matrix -= matrix
      matrix .*= matrix
      matrix ./= matrix

      matrix += scalar
      matrix -= scalar
      matrix *= scalar
      matrix /= scalar

      logical matrix |= logical matrix
      logical matrix &= logical matrix

    where matrix and scalar belong to the same class.  The left-hand
    side must be a simple variable reference.

    Moreover, when unary operators occur in expressions, Octave will
    also try to do the operation in-place if it's argument is a
    temporary expresssion.

 ** The effect of comparison operators (<, >, <=, and >=) applied to
    complex numbers has changed to be consistent with the strict
    ordering defined by the `max', `min', and `sort' functions.  More
    specifically, complex numbers are compared by lexicographical
    comparison of the pairs `[abs(z), arg(z)]'.  Previously, only real
    parts were compared; this can be trivially achieved by wrapping the
    operands in real().

 ** The automatic simplification of complex computation results has
    changed.  Octave will now simplify any complex number with a zero
    imaginary part or any complex matrix with all elements having zero
    imaginary part to a real value.  Previously, this was done only for
    positive zeros.  Note that the behavior of the complex function is
    unchanged and it still produces a complex value even if the
    imaginary part is zero.

 ** As a side effect of code refactoring in liboctave, the binary
    logical operations are now more easily amenable to compiler
    optimizations and are thus significantly faster.

 ** Octave now allows user-defined `subsasgn' methods to optimize out
    redundant copies.  For more information, see the manual.

 ** More efficient matrix division handling.  Octave is now able to
    handle the expressions

       M' \ V
       M.' \ V
       V / M

    (M is a matrix and V is a vector) more efficiently in certain cases.
    In particular, if M is triangular, all three expressions will be
    handled by a single call to xTRTRS (from LAPACK), with appropriate
    flags.  Previously, all three expressions required a physical
    transpose of M.

 ** More efficient handling of certain mixed real-complex matrix
    operations.  For instance, if RM is a real matrix and CM a complex
    matrix,

      RM * CM

    can now be evaluated either as

      complex (RM * real (CM), RM * imag (CM))

    or as

      complex (RM) * CM,

    depending on the dimensions.  The first form requires more
    temporaries and copying, but halves the FLOP count, which normally
    brings better performance if RM has enough rows.  Previously, the
    second form was always used.

    Matrix division is similarly affected.

 ** More efficient handling of triangular matrix factors returned from
    factorizations.  The functions for computing QR, LU and Cholesky
    factorizations will now automatically return the triangular matrix
    factors with proper internal matrix_type set, so that it won't need
    to be computed when the matrix is used for division.

 ** The built-in `sum' function now handles the non-native summation
    (i.e., double precision sum of single or integer inputs) more
    efficiently, avoiding a temporary conversion of the whole input
    array to doubles.  Further, `sum' can now accept an extra option
    argument, using a compensated summation algorithm rather than a
    straightforward sum, which significantly improves precision if lots
    of cancellation occurs in the summation.

 ** The built-in `bsxfun' function now uses optimized code for certain
    cases where built-in operator handles are passed in.  Namely, the
    optimizations concern the operators `plus', `minus', `times',
    `ldivide', `rdivide', `power', `and', `or' (for logical arrays),
    the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the
    functions `min' and `max'.  Optimizations only apply when both
    operands are of the same built-in class.  Mixed real/complex and
    single/double operations will first convert both operands to a
    common type.

 ** The `strfind' and `strrep' functions now have compiled
    implementations, facilitating significantly more efficient searching
    and replacing in strings, especially with longer patterns.  The code
    of `strcat' has been vectorized and is now much more efficient when
    many strings are concatenated.  The `strcmpi' and `strncmpi'
    functions are now built-in functions, providing better performance.

 ** Matlab-style ignoring input and output function arguments using
    tilde (~) is now supported.  Ignored output arguments may be
    detected from a function using the built-in function `isargout'.
    For more details, consult the manual.

 ** The list datatype, deprecated since the introduction of cells, has
    been removed.

 ** The accumarray function has been optimized and is now significantly
    faster in certain important cases.

 ** The behavior of isreal and isnumeric functions was changed to be more
    Matlab-compatible.

 ** The integer math & conversion warnings (Octave:int-convert-nan,
    Octave:int-convert-non-int-val, Octave:int-convert-overflow,
    Octave:int-math-overflow) have been removed.

 ** rem and mod are now built-in functions.  They also handle integer
    types efficiently using integer arithmetic.

 ** Sparse indexing and indexed assignment has been mostly rewritten.
    Since Octave uses compressed column storage for sparse matrices,
    major attention is devoted to operations manipulating whole columns.
    Such operations are now significantly faster, as well as some other
    important cases.

    Further, it is now possible to pre-allocate a sparse matrix and
    subsequently fill it by assignments, provided they meet certain
    conditions.  For more information, consult the `spalloc' function,
    which is no longer a mere dummy.  Consequently, nzmax and nnz are no
    longer always equal in Octave.  Octave may also produce a matrix
    with nnz < nzmax as a result of other operations, so you should
    consistently use nnz unless you really want to use nzmax (i.e. the
    space allocated for nonzero elements).

    Sparse concatenation is also affected, and concatenating sparse
    matrices, especially larger collections, is now significantly more
    efficient.  This applies to both the [] operator and the
    cat/vertcat/horzcat functions.

 ** It is now possible to optionally employ the xGESDD LAPACK drivers
    for computing the singular value decomposition using svd(), instead
    of the default xGESVD, using the configuration pseudo-variable
    svd_driver.  The xGESDD driver can be up to 6x times faster when
    singular vectors are requested, but is reported to be somewhat less
    robust on highly ill-conditioned matrices.

 ** Configuration pseudo-variables, such as page_screen_output or
    confirm_recursive_rmdir (or the above mentioned svd_driver), now
    accept a "local" option as second argument, requesting the change
    to be undone when the current function returns:

    function [status, msg] = rm_rf (dir)
      confirm_recursive_rmdir (false, "local");
      [status, msg] = rmdir (dir, "s");
      ...
    endfunction

    Upon return, confirm_recursive_rmdir will be restored to the value
    it had on entry to the function, even if there were subsequent
    changes to the variable in function rm_rf or any of the functions
    it calls.

 ** pkg now accepts a -forge option for downloading and installing
    packages from Octave Forge automatically.  For example,

      pkg install -forge general

    will automatically download the latest release of the general
    package and attempt to install it. No automatic resolving of
    dependencies is provided.  Further,

      pkg list -forge

    can be used to list all available packages.

  ** The internal data representation of structs has been completely
     rewritten to make certain optimizations feasible.  The field data
     can now be shared between structs with equal keys but different
     dimensions or values, making operations that preserve the fields
     faster.  Economized storage is now used for scalar structs (just
     like most other scalars), making their usage more
     memory-efficient.  Certain array-like operations on structs
     (concatenation, uniform cellfun, num2cell) have gained a
     significant speed-up.  Additionally, the octave_scalar_map class
     now provides a simpler interface to work with scalar structs within
     a C++ DLD function.

  ** Two new formats are available for displaying numbers:

       format short eng
       format long eng

     Both display numbers in engineering notation, i.e., mantissa +
     exponent where the exponent is a multiple of 3.

  ** The following functions are new in Octave 3.4:

       accumdim    erfcx        nfields      pqpnonneg  uigetdir
       bitpack     fileread     nth_element  quadcc     uigetfile
       bitunpack   fminbnd      onCleanup    randi      uiputfile
       blkmm       fskipl       pbaspect     repelems   uimenu
       cbrt        ifelse       pie3         reset      whitebg
       curl        ishermitian  powerset     rsf2csf
       chop        isindex      ppder        saveas
       daspect     luupdate     ppint        strread
       divergence  merge        ppjumps      textread

  ** Using the image function to view images with external programs such
     as display, xv, and xloadimage is no longer supported.  The
     image_viewer function has also been removed.

  ** The behavior of struct assignments to non-struct values has been
     changed.  Previously, it was possible to overwrite an arbitrary
     value:

        a = 1;
        a.x = 2;

     This is no longer possible unless a is an empty matrix or cell
     array.

  ** The dlmread function has been extended to allow specifying a custom
     value for empty fields.

  ** The dlmread and dlmwrite functions have been modified to accept
     file IDs (as returned by fopen) in addition to file names.

  ** Octave can now optimize away the interpreter overhead of an
     anonymous function handle, if the function simply calls another
     function or handle with some of its parameters bound to certain
     values.  Example:

       f = @(x) sum (x, 1);

     When f is called, the call is forwarded to @sum with the constant 1
     appended, and the anonymous function call does not occur on the
     call stack.

 ** Deprecated functions.

    The following functions were deprecated in Octave 3.0 and have been
    removed from Octave 3.4.

  * For compatibility with Matlab, mu2lin (x) is now equivalent to
    mu2lin (x, 0).

  * The ARPACK library is now distributed with Octave so it no longer
    needs to be available as an external dependency when building
    Octave.

as executables rather than loadable modules
This might cause that the pkg doesn't build on as many platforms as
it did before, but it has a chance to work now.

Summary of changes for version 2.0.17:
-------------------------------------

  This will probably be the last release in the 2.0.x series.  There
  are a few bug fixes, but the major change is to print a message
  saying that Octave 2.0.x cannot be compiled with gcc 3.0.x or gcc
  2.96.  If you want to build Octave 2.0.x, you will need to use gcc
  2.95.x.  If you want to use gcc 3.0.x or some later version, you
  should be using the Octave 2.1.35 sources or a more recent version.

Introduce new framework for handling info files generation and installation.

Summary of changes:
- removal of USE_GTEXINFO
- addition of mk/texinfo.mk
- inclusion of this file in package Makefiles requiring it
- `install-info' substituted by `${INSTALL_INFO}' in PLISTs
- tuning of mk/bsd.pkg.mk:
    removal of USE_GTEXINFO
    INSTALL_INFO added to PLIST_SUBST
    `${INSTALL_INFO}' replace `install-info' in target rules
    print-PLIST target now generate `${INSTALL_INFO}' instead of `install-info'
- a couple of new patch files added for a handful of packages
- setting of the TEXINFO_OVERRIDE "switch" in packages Makefiles requiring it
- devel/cssc marked requiring texinfo 4.0
- a couple of packages Makefiles were tuned with respect of INFO_FILES and
  makeinfo command usage

See -newly added by this commit- section 10.24 of Packages.txt for
further information.

make sure this configures and builds correctly with either f77 or f2c.
