This patch fixes libgm2/libm2iso/wraptime.cc:InitTM so that
it does not always return NULL.  The incorrect autoconf macro
was used (inside InitTM) and the function short circuited
to return NULL.  The fix is to use HAVE_SYS_TIME_H and use
AC_HEADER_TIME in libgm2/configure.ac.

	PR modula2/115276
	* config.h.in: Regenerate.
	* configure: Regenerate.

	before using struct tm to obtain the size.

Like in r12-7519-g027e30414492d50feb2854aff38227b14300dc4b, I've done
git grep -v 'long long\|optab optab\|template template\|double double' | grep ' \([a-zA-Z]\+\) \1 '

This is just part of the changes, mostly for non-gcc directories.
I'll try to get to the rest soon.  Obviously, the above command also
finds cases which are correct as is and shouldn't be changed, so one
needs to manually inspect everything.

I'd hope most of it is pretty obvious, but the config/ and libstdc++-v3/
hunks include a tweak in a license wording, though other copies of the
similar license have the wording right.

As it turned out, my patch to complete the libgm2 autoconf macros works
on both Linux/sparc64 and Linux/x86_64, but breaks Solaris bootstrap:

This happens because on Linux only HAVE_[GS]ETTIMEOFDAY is defined,
while Solaris has both that and HAVE_STRUCT_TIMEZONE, selecting
different implementations.

Fixed by casting tv to struct timeval *.

I thought about changing the signatures instead to take a struct timeval
* instead, but that seemed risky given that there's a
HAVE_STRUCT_TIMEVAL, so would probably break other targets.

Bootstrapped without regressions on i386-pc-solaris2.11,
sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.

2024-02-13  Rainer Orth  <ro@CeBiTec.Uni-Bielefeld.DE>

	libgm2:
	* libm2iso/wraptime.cc [HAVE_STRUCT_TIMEZONE && HAVE_GETTIMEOFDAY]
	(EXPORT(gettimeofday)): Cast tv to struct timeval *.
	[HAVE_STRUCT_TIMEZONE && HAVE_SETTIMEOFDAY]
	(EXPORT(settimeofday)): Likewise.

As detailed in PR modula2/113888, the 32-bit libm2pim/target.c doesn't
assemble in a Linux/sparc64 multilib build.  However, the root cause is
that the HAVE_EXP10* macros are never defined.  While I was at it, I
checked for other cases where the code uses HAVE_* macros that are
missing from config.h.in.

This patch adds the missing checks, changes the configure checks where
the names don't match what's used in the code, or corrects the code to
use the right names.

So far tested on sparc64-unknown-linux-gnu by building libgm2 (32 and
64-bit) and running the gm2 tests.

r14-4149-g81d5ca0b9b8431f1bd7a5ec8a2c94f04bb0cf032 which assummed

ensures that cc1gm2 obtains the default IEEE754 long double availability
from the configure generated tm_defines.  The user command
line switches -mabi=ibmlongdouble and -mabi=ieeelongdouble are implemented
to override the configuration defaults.

While investigating possible race conditions in the GCC testsuites
caused by bufferization issues, I wanted to investigate workarounds
similar to GDB's READ1 [1], and I noticed it was not always possible
to override EXPECT when running 'make check'.

This patch adds the missing support in various Makefiles.

I was not able to test the patch for all the libraries updated here,
but I confirmed it works as intended/needed for libstdc++.

libatomic, libitm, libgomp already work as intended because their
Makefiles do not have:
MAKEOVERRIDES=

Tested on (native) aarch64-linux-gnu, confirmed the patch introduces
the behaviour I want in gcc, g++, gfortran and libstdc++.

I updated (but could not test) libgm2, libphobos, libquadmath and
libssp for consistency since their Makefiles have MAKEOVERRIDES=

libffi, libgo, libsanitizer seem to need a similar update, but they
are imported from their respective upstream repo, so should not be
patched here.

wrapclock.cc.  The conditional section in wrapclock_timezone
should return 0 rather than return timezone.

libgm2/ChangeLog:

	PR modula2/112110
	* libm2iso/wrapclock.cc (timezone): Return 0 if unable
	to get the timezone from the tm struct.

This patch uses the libiberty getopt long functions (wrapped up inside
libgm2/libm2pim/cgetopt.cc) and only enables this implementation if
libgm2/configure.ac detects no getopt_long and friends on the target.

an isnan definition and support functions to gm2-gcc/m2builtins.cc.

Recent Darwin versions place contraints on the use of run paths
specified in environment variables.  This breaks some assumptions
in the GCC build.

This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).

The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.

For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).

During build-time configurations  any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.

Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).

This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.

We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier.  For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).

ChangeLog:

	* configure: Regenerate.
	* configure.ac: Do not add default runpaths to GCC exes
	when we are building -static-libstdc++/-static-libgcc (the
	default).
	* libtool.m4: Add 'enable-darwin-at-runpath'.  Act  on the
	enable flag to alter Darwin libraries to use @rpath names.

This patch corrects the C equivalent of m2 LONGINT parameters
in wrapclock.cc and corrects the SysClock.mod module.
wrapclock.cc uses a typedef long long int longint_t to match
m2 LONGINT (rather than unsigned long).  These fixes
prevent calls to SysClock hanging spinning on an (incorrect)
large day count from the epoch.

gcc/m2/ChangeLog:

	* gm2-compiler/M2Quads.mod (EndBuildFor): Improve
	block comments.
	* gm2-libs-iso/SysClock.mod (ExtractDate): Replace
	testDays with yearOfDays.  New local variable monthOfDays.

	(GetTimespec): Replace types for sec and nano with
