Include <arpa/inet.h> for htonl()  (From Jan-Benedict Glaw)
Probably this should be using htobe32() instead of htonl()
(and so <endian.h> rather than <arpa/inet.h>) as there is
no sign of any network anywhere near here.   But that's for
another day, and to be done by someone who can test it.

Portability fixes from Jan-Benedict Glaw
The args to help() and usage() need to be const char *
and main() should be declared as returning int.

Add shquote to libnbcompat
Include shquote() in configure tests
Regen for added shquote()

Stop attempting to return a (char*) in place of (const char *)
This removes a cast that was added in 1994, when __strsignal()
returned a char * to convert the const char * element of sys_siglist
into a type that matched.

It should have been removed when __strsignal() was changed to
return const char * in 1998.   But wasn't.

This should fix an inane warning (treated as an error) from a
compile stupid enough to allow a natural char * (as in char buf[N])
to be returned as a result (which is, of course, fine), but complains
about returning (char *) applied to a (const char *).

Include shquote() in configure tests

tools: binstall can use posix_spawn() instead of vfork()

tools/compat: provide nb_check_cc_flag.m4

Implement m4 macro NB_CHECK_CC_FLAG(FLAG, [VAR=FLAG_DERIVED])
	Determine if the C compiler supports FLAG,
	and sets output variable VAR to FLAG if FLAG is supported.

	If VAR is not provided, default to FLAG_DERIVED, which is
	FLAG converted to upper-case and all special characters
	replaced with "_", and the result prepended with "CC_".
	FLAG_DERIVED is appended to the m4 macro NB_CHECK_CC_FLAG_VARS.
	E.g., if FLAG is "-Wexample=yes", FLAG_DERIVED is "CC_WEXAMPLE_YES".

This is implemented in separate buildaux/nb_check_cc_flag.m4,
based on configure's NB_CC_FLAG(), but supports VAR override.

Adapt configure from internal NB_CC_FLAG() to NB_CHECK_CC_FLAG().

(Note: AX_CHECK_COMPILE_FLAG() from autoconf-archive could be enhanced
to support the clang and gcc workarounds I've implemented here.)

ctfmerge: error check sem_*() and pthread_*() APIs

terminate() if sem_*() returns -1 or pthread_*() returns != 0.
(Set errno from pthread_*() so terminate() prints the strerror message).

Note: Failing on errors instead of ignoring them helps identify
reasons for intermittent failures, such as those on macOS host builds:

  ERROR: nbctfmerge: barrier_init: sem_init(bar_sem): Function not implemented

ctfmerge: fix macOS semaphore implementation

Use dispatch_semaphore_create() if present instead of sem_init().
macOS doesn't actually implement sem_init() (et al)
(even though it provides the prototypes as deprecated).

This was detected by the previous commit to ctfmerge
that added error handling.

Implement ctfmerge's barrier operations in terms of
dispatch(3) APIs such as dispatch_semaphore_create() (et al).

Update tools/compat/configure.ac to find dispatch_semaphore_create().
Fixes ctfmerge on macOS hosts.

tools/compat: regen for dispatch_semaphore_create

ctfmerge: fix macOS semaphore implementation, part 2
dispatch_semaphore_signal() doesn't return an error, just an
indicator of whether a thread was woken or not, so there's
no need to fail on non-zero return.

osnet: on macOS, use <mach/boolean.h> for boolean_t
macOS/x86_64 defines boolean_t as 'unsigned int' not 'int',
which causes a build issue with tools/ctfmerge on that host
after my recent fixes for macOS semaphores.

So use the <mach/boolean.h> instead of a local typedef ifdef __APPLE__.
May fix a macOS/x86_64 build issue reported by cjep@.
Builds fine on NetBSD/amd64 or macOS/arm.

Note: this compat stuff is clunky, and based on the commit log,
annoyingly error prone. A newer sync of osnet from upstream /may/
improve a lot of these compat typedef workarounds for solaris types...

tools/compat: support all bsd.own.mk disabled warnings

Check the host CC support for all the warnings now in <bsd.own.mk>
and override appropriately in defs.mk.

In general there's a 1:1 mapping, with the special case
CC_WNO_ADDRESS_OF_PACKED_MEMBER which is set from both
@CC_WNO_ADDRESS_OF_PACKED_MEMBER@ (gcc) and
@CC_WNO_ERROR_ADDRESS_OF_PACKED_MEMBER@ (clang).

tools/compat: disable host CC warnings

Determine if the host CC supports flags to disable various
warnings similar to <bsd.own.mk> GCC_*, CLANG_*, and CC_*,
and override the <bsd.own.mk> equivalents in defs.mk.

Silences "warning: unknown warning option '...'" from our source.
External source (e.g., binutils and gcc) need their own fixes
to enhance their detection of supported clang compiler flags.

tools/compat: detect supported host compiler flags

Define NB_CC_FLAG(FLAG) to use AX_CHECK_COMPILE_FLAG
to determine if the host compiler supports FLAG
and define and AC_SUBST CC_FLAG if so.

Use workarounds to force clang to hard-fail on unknown -Wwarning,
and gcc to use -WWARN to check unknown -Wno-WARN because the
latter doesn't cause an error in gcc.

In the future we could use NB_CC_FLAG([-fcommon]) for
older NetBSD release branches compiled with host gcc 10+.

Rework Darwin -no-cpp-precomp check to use NB_CC_FLAG().
Note: this flag probably hasn't been required on macOS (Darwin)
for a long time, but serves as a good example on how to use this.

Display varaibles at the end of configure to show what was detected.

tools/compat: don't expose HAVE_PTHREAD_H to make

Non of the tools Makefiles needs HAVE_PTHREAD_H, so don't
AC_SUBST it or provide in defs.mk.

tools/compat/configure.ac: style tweaks

Use "NB_" prefix not "AC_" for our macros ("AC_" is for autoconf).
Fail is NB_ macro isn't defined.
Use AC_DEFUN() instead of define().
Consistently use () in zero argument macro calls.

ctfmerge: fix macOS semaphore implementation

Use dispatch_semaphore_create() if present instead of sem_init().

macOS doesn't actually implement sem_init() (et al)
(even though it provides the prototypes as deprecated).
This was detected by the previous commit to ctfmerge

Make using autoheader easier:
split off the autogenerated file into nbtool_config_internal.h,
and let nbtool_config.h be a file with the proper wrappers.

This way you can just change configure.ac, run autoconf and autoheader,
verify the result, and commit, but don't have to edit nbtool_config*in
manually every time.

HAVE_SYS_POLL_H is used by src/include/roken.h needed by the host tool asn1_compile

Overhaul how `build.sh tools' are used:

    *	Rename "config.h" to "nbtool_config.h" and
	HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
	This makes in more obvious in the source when we're using
	tools/compat/config.h versus "standard autoconf" config.h

    *	Consistently move the inclusion of nbtool_config.h to before
    	<sys/cdefs.h> so that the former can provide __RCSID() (et al),
    	and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
	#if HAVE_NBTOOL_CONFIG_H
	#include "nbtool_config.h"
	#endif
to the top of the source files (for the general case).

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

Add a putc_unlocked().

Fix the socklen_t test; we need to explcitly list the headers we want
included for that test.

Check for sys/socket.h and socklen_t.

Include <sys/types.h> before <grp.h>; Mac OS 10.2.2 needs this.

Include <sys/types.h> before including <dirent.h>; Mac OS 10.2.2
needs this.

Pull up revision 1.24 (requested by thorpej in ticket #834):
  Always NetBSD's own fts(3) in compat builds.  Some systems
  (among them RedHat 7.3) do not have fts(3) implementations
  which work correctly with -D_FILE_OFFSET_BITS=64.

add check back for util.h; needed on some foreign systems

Pull up revision 1.23 (via patch, requested by thorpej in ticket #807):
   o Check for mkstemp() and mkdtemp(), and build them into
     libcompat if necessary.
   o mktemp is now a host-tool, so remove the now obsoleted
     script.

- Migrate fparseln(3) from libutil to libc, where it should have been in
  the first place...
- Bump libutil major (to 7.0) and libc minor (to 12.91).

replace missing strsuftoll(3)

Pull up revision 1.22 (via patch, requested by thorpej in ticket #797):
  Include various more functions in libnbcompat, mostly
  becuase our tools use features not universally present in
  other versions. This applies to glob(3), vis(3), and the
  MD2, MD4, RMD160 and SHA1 implementations.
  Also add checks for random(3) and termios.h for the Heimdal
  host tools.
  Update README to indicate the current state of building the
  host tools on Solaris 8 (for SPARC).

Just check for poll.h, don't fail if it's not present.

Provide strtoll() in libnbcompat.
Should fix relevant build issue on HP-UX and MacOS X hosts.

check for lchflags

Check for <poll.h> and poll(2).

Always use NetBSD's fts(3) in compat builds.  Some systems (notably
Red Hat 7.3, at least) do not have fts(3) implementations that work
correctly with -D_FILE_OFFSET_BITS=64.

* Check for mkstemp() and mkdtemp(), and build them into libnbcompat
  if necessary.
* mktemp is now a host-tool, so nuke the lame script (which isn't even
  properly installed during the tools bootstrap).

* Always include the NetBSD glob(3) in libnbcompat, as the host
  tools use some features of glob(3) that are not available on
  all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
  is not really standardized, and the vis(3) present on some systems
  is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
  in libnbcompat.  The host tools use features of the NetBSD versions
  which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.
* Update the README to indicate the current state of building the
  host tools on Solaris 8 (for SPARC).

Fine-grain checking somewhat:
* check for user_from_uid() in addition to pwcache_userdb()
* check for svis() in addition to vis()

Rather than hardcoding two possible locations of the POSIX shell (for
Solaris and everything else), set _PATH_BSHELL to the first occurrence of
"sh" on the path.  This should be rather more portable.

Add test for alloca() and <alloca.h>, since Sun Workshop C 5.0 needs this.

Create sys/endian.h if it doesn't exist, since rmd160.c includes it directly.

Emit an empty <stdint.h> if the host doesn't have one.  Should fix PR 16416.

Re-add test for <sys/endian.h>; it disappeared somewhere along the way.

Add a stub issetugid() for platforms that don't have it.  For now, we assume
that no host program will be installed set-id, so the stub function always
returns 0.

Revert addition of mkdtemp() to libnbcompat.  I don't think we need mktemp(1)
after all.

Add mkdtemp to libnbcompat, since glibc doesn't have it an mktemp(1) will
need it.

Add the md[245], sha1 and rmd160 functions to libnbcompat, conditional on their
not being in the host libc.
This will be necessary to make cksum into a host tool.

Don't gratuitously touch the replacement headers in ${.OBJDIR}/include;
instead, touch them only if they're changed.

Move inttypes.h to list of auto-generated-empty headers.

Add compat defns for uint*_t (the non-underscored ones).
[The logic in all of this is ugly, and should instead be fixed up to use
AC_CHECK_SIZEOF to use primitives if the counterpart type is unavailable.]

Add some more bits of host compatibility.

Roll in fixes to permit cross-compiling from non-NetBSD hosts.  This
round has been tested on Solaris/x86 and Linux hosts.

* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
  sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.

Make almost all tools compile and run properly on non-NetBSD hosts.  (In
particular, most tools now run correctly on Solaris 7.)

- Replace pwcache(3) if necessary (pwcache_userdb(3) is checked for).
  Tested on -current and 1.5.3.
- Wrap some long lines.

Make many host tools compile on non-NetBSD hosts.  Not complete, but
very nearly there.

look for <inttypes.h> and #include if found (for uint*_t)

Add replacement fgetln(3) (from lukemftp/libukem), as fparseln(3) uses it

Add the framework for autoconf-based src/tools/compat structure.  This will
(after it is more fleshed out) allow the host tools to work more cleanly
on non-NetBSD hosts.
