ksh: suppress the 435 lint warnings about identifier list definitions

Leave the actual work of modernizing the function definitions to some
later day.

ksh: clean up Makefile

adapt to ${CC_WNO_IMPLICIT_FALLTHROUGH}

Use ${CC_WNO_IMPLICIT_FALLTHROUGH} instead of
the older style more complex expressions.

Ooops, restore accidently removed files from merge mishap

Sync with HEAD

Mostly merge changes from HEAD upto 20200411

convert HAVE_GCC == 7 to HAVE_GCC >= 7.

Sync with HEAD

- use -Wno-error=implicit-fallthrough with GCC7.

ksh: Drop support for OSes without POSIX sigaction(2)

Put back awk, other scripts need it.

We don't need all this magic to build the signals lists. Do the work at
compile time.

Skip vendor if the string is empty.
Use l_wmesg if the string is not empty. Don't bother checking l_name for
nullness.

Make cast warnings for clang non-fatal.

Make cast warnings for clang non-fatal.

Don't use non-literal format strings.

kill gcc-4.5 hack.

apply some -Wno-error and/or -fno-strict-aliasing.


all of this should be looked at closer, but some of them are not
very trivial.

Default to -Wno-sign-compare -Wno-pointer-sign for clang.
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.

Sync with HEAD.

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

Default to WARNS=4 (except for rcp & ksh)

Pass SED=${TOOL_SED:Q} in the environment to scripts run during the build.

Pass AWK in environment to shell scripts run during the build.

warns=3
- remove param names from function decls
- sprinkle const
- rename shadowed variables
- XXX: there is a lot of fishy __UNCONST going on.

don't need -DHAVE_CONFIG_H here

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Rework how MAKEVERBOSE operates:

    *	Don't bother prefixing commands with a line of  ${_MKCMD}\
	and instead rely upon "make -s".  This is less intrusive on
	all the Makefiles than the former.  Idea from David Laight.

    *	Rename the variables use to print messages.  The scheme now is:
	    _MKMSG_FOO		Run  _MKMSG 'foo'
	    _MKTARGET_FOO	Run  _MKMSG_FOO ${.TARGET}
	From discussion with Alistair Crooks.

rework to use the newer _MKMSGCREATE (et al) macros

support MAKEVERBOSE

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
  This is a change of behaviour.  If a Makefile wants the clean semantics
  it must specifically append to CLEANFILES.
  Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
  that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d  depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

Pull up revisions 1.14-1.16 (requested by dogcow):
  Synchronize with current development version:
   o fix problem with ``set -x'' causing a core dump; fixes PR#11361
   o fix problem with ``set -e'' causing early exit; fixes PR#11542
   o fix various misspellings and nested extern declarations

default to WARNS=1 if not set

Don't build ksh.1 if MKMAN == "no".

Pull up rev 1.13:
> date: 2000/06/22 05:42:22;  author: soren;  state: Exp;  lines: +3 -1

$(CPP) -> $(CC) -E

CLEANFILES+= siglist.out emacs.out

Pull up to last week's -current.

Remove WARNS=1 from all the subdirectory Makefiles, and add it to Makefile.inc
now that all /bin has been cleaned.

Fix compiler warnings
Add WARNS=1

Use DPSRCS.

Eliminate bogus redefinitions of standard targets.

close pr-3111 -- use sh to invoke script instead of executing

RCS ID Police

Removed missing.c beacuse NetBSD is not missing any of the functions
that it provides.
