Some distro may ship dangling symlinks in include directories, triggers
the access failure. Skip it and continue to next header instead of

Restore to old behavior before r12-5234 but without resurrecting the
problematic getcwd() call, by using the environment variable "INPUT"
exported by fixinc.sh.
Tested on x86_64-linux-gnu, with a dangling symlink intentionally
injected into /usr/include.

* fixincl.c (process): Don't call abort().
POSIX says:
On some implementations, if buf is a null pointer, getcwd() may obtain
size bytes of memory using malloc(). In this case, the pointer returned
by getcwd() may be used as the argument in a subsequent call to free().
Invoking getcwd() with buf as a null pointer is not recommended in
conforming applications.
This produces an error building GCC with --enable-werror-always:
../../../fixincludes/fixincl.c: In function ‘process’:
../../../fixincludes/fixincl.c:1356:7: error: argument 1 is null but
the corresponding size argument 2 value is 4096 [-Werror=nonnull]
It's suggested by POSIX to call getcwd() with progressively larger
buffers until it does not give an [ERANGE] error. However, it's highly
unlikely that this error-handling route is ever used.
So we can simplify it instead of writting too much code. We give up to
use getcwd(), because `make` will output a `Leaving directory ...` message
containing the path to cwd when we call abort().

AIX protects the STDC Format Macros in a manner that can prevent the
definition of the macros depending on the order of header inclusion.
The protection of the macros was referenced in C99, removed in C11, and
never specified in any C++ standard. Also, the macros are in the namespace
reserved to the implementation (compiler) so the compiler is permitted to
choose to inject those names.

mkheaders.in uses substitutions of @SHELL@ to run fixinc.sh and
mkinstalldirs. Problem is, SHELL comes from CONFIG_SHELL for the
build system, and it needs not match whatever is available at an
unrelated host system after installation, when mkheaders is supposed
to be run.
I considered ditching the hardcoding altogether, but decided to retain
it, but allowing CONFIG_SHELL and SHELL to override it, if any of them
can successfully run mkinstalldirs, and if those and the substituted
@SHELL@ fail, fallback to /bin/sh and to plain execution of the
script, which appears to enable at least one shell on a system that
doesn't typicall have a shell to recognize a script by #!/bin/sh and
reinvoke itself to run it.
If all of these fail, we fail, but only after telling the user to
retry after setting CONFIG_SHELL, that fixincl itself also uses.

Some system headers can be broken by the machine_name fix performed
by GCC during the fixincludes step. According to the comment in
fixincludes/fixinc.h:130 :
On some platforms, machine_name doesn't work properly and
breaks some of the header files. Since everything works
properly without it, just wipe the macro list to
disable the fix.
So we can just skip it to avoid trouble.

* fixinc.in: Skip machine_name fix on powerpc*-*-linux*.
vxworks7 headers haven't required fixes, and we've decided to avoid
running fixinc on them.
The problem with that is that, with a dummy fixinc, mkheaders wipes
out include-fixed but then multi_dir subdirs are not created again, so
we end up with a limits.h named after each multi_dir, when there are
non-default multilibs. Oops.
This patch arranges for a dummy fixinc to be created for *-*-vxworks7*
targets, and fixes mkheaders so as to create multi_dir subdirs in
include-fixed after wiping them out, and to copy limits.h so that it
won't take the name that should be of a subdir (unless the multi_dir
is limits.h, but that's hopefully never the case ;-)
for fixincludes/ChangeLog
* mkheaders.in: Re-create subdirs, copy limits.h into subdir.
* mkfixinc.sh: Create dummy fixinc for *-*-vxworks7*.
There is no reasonable chance that the SDKs in question will be re-
issued, so the only viable solution is a fixincludes.

Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers. However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10. This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__. The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.
This fixes the tr1 testsuite fails seen on Darwin9 and 10.

This patch updates GCC to use autoconf 2.69 and automake 1.15.1.
(That's not the latest automake version, but it's the one used by
binutils-gdb, with which consistency is desirable, and in any case
seems a useful incremental update that should make a future update to
1.16.1 easier.)
The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf. Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree. Autoconf 2.69 has Go support, so
local copies of that support are removed. I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update. Changes to how automake generates
runtest calls mean quotes are removed from RUNTEST definitions in five
lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm,
libphobos, libvtv; some others have RUNTEST definitions without
quotes, which are still OK); libgo and libphobos also get
-Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST
do not generate automake warnings.
Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory). Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.
While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers. Specifically, most of those warnings
were of the following form (example from libgfortran):
Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed. In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.
I've tested this with native, cross and Canadian cross builds. The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

A quick experiment reveals that this hack is needed for C code - simply
removing this hack entirely breaks the build of libstdc++, since
regs.h (more accurately, the cpu-specific header it pulls in) defines
structs in terms of types from vxTypesOld. Those definitions are
properly guarded by #ifndef _ASMLANGUAGE, but the cpu-files do not take
care to include vxTypesOld.h for the types they depend on.
But when using regs.h from some assembly file, the assembler chokes on
the typedefs in vxTypesOld.h. We can fix that by guarding the include of
vxTypesOld by !_ASMLANGUAGE. This should not affect existing C code.
Now, the OS' regs.h contains preprocessor conditionals such as
#if CPU_FAMILY==I960
...
#endif /* CPU_FAMILY==I960 */
#if CPU_FAMILY==MC680X0
...
#endif /* CPU_FAMILY==MC680X0 */
Without definitions of CPU_FAMILY, I960 etc., these would all be true,
which will not end well. Code using the fix-included regs.h
automatically get vxCpu.h via a chain of includes from vxTypesOld.h, but
we can make regs.h a little more self-contained for both C and asm users
by doing an explicit include of vxCpu.h.

The rationale for the fixinclude ioctl macro wrapper is, as far as I can
tell (https://gcc.gnu.org/ml/gcc-patches/2012-09/msg01619.html)
Fix 2: Add hack for ioctl() on VxWorks.
ioctl() is supposed to be variadic, but VxWorks only has a three
argument version with the third argument of type int. This messes up
when the third argument is not implicitly convertible to int. This
adds a macro which wraps around ioctl() and explicitly casts the third
argument to an int. This way, the most common use case of ioctl (with
a const char * for the third argument) will compile in C++, where
pointers must be explicitly casted to int.
However, we have existing C++ code that calls the ioctl function via
::ioctl(foo, bar, baz)
and obviously this breaks when it gets expanded to
::(ioctl)(foo, bar, (int)(baz))
Since the GNU C preprocessor already prevents recursive expansion of
function-like macros, the parentheses around ioctl are unnecessary.
Incidentally, there is also a macro sioIoctl() in the vxworks sioLib.h
header that expands to
((pSioChan)->pDrvFuncs->ioctl (pSioChan, cmd, arg))
which also breaks when that gets further expanded to
((pSioChan)->pDrvFuncs->(ioctl) (pSioChan, cmd, (int)(arg)))
This patch partly fixes that issue as well, but the third argument to
the pDrvFuncs->ioctl method should be void*, so the cast to (int) is
slightly annoying. Internally, we've simply patched the sioIoctl macro:
(((pSioChan)->pDrvFuncs->ioctl) (pSioChan, cmd, arg))

When adding the vxworks_iolib_include_unistd hack I failed to add the
appropriate hunk to the tests/base/ioLib.h file, causing "make
check-fixincludes" to fail.
