* This changes the optimization level from -O3 to -O
* This will prevent segfaults when creating jam via the Makefile on FreeBSD
* Benchmarking was done, and there seems to be no negative performance impact
* Another option would be -O3 -fno-strict-aliasing, but this has no noticeable benefit over -O
* This update resolves the segfault/ICE in gcc/c-parser.c while building natively
* gcc/gengtype.c was already updated to GCC 4.6.3 version previously in btrev43031, so no change there
* gcc/libiberty/make-relative-prefix is the stock 4.6.3 version now, as the workaround for Haiku is no longer needed
* This update is otherwise the GCC patches for upgrading 4.6.2 to 4.6.3 core/g++ applied to our sources
* A build failure occurs as TARGET_64BIT is no longer a compile-time
constant in GCC.
* Made some changes so that generated code matches the i386 Haiku target when
generating 32-bit code, and follows the x86_64 ABI for 64-bit code.
* Added a comment stating that DEFAULT_PCC_STRUCT_RETURN needs to be defined
to follow the ABI for 32-bit code, it is ignored for 64-bit.
* Remove definition of __x86_64__, already defined by GCC's i386-c.c.
* Remove -z max-page-size from LINK_SPEC as it shouldn't be necessary: the
default page size is 2MB but this won't result in large binaries, it just
changes the alignment of the sections and would make it easier to map
binaries using large pages in the future.

* arm: ASM_COMMENT_START is defined in arm/aout.h.
* i386 and x86_64: define ASM_COMMENT_START.
* others: ASM_COMMENT_START is defined in ${arch}/${arch}.h.
If you take a release tarball (which has pregenerated syslex and sysinfo files
in it), apply some patches which touch syslex.l, and then build the result out
of tree, it will fail. This is because syslex.l uses sysinfo.h, but the
sysinfo.y file wasn't updated and so it wasn't regenerated (the files are found
in the $srcdir), and the build rule for syslex.c does not use -I$(srcdir) when
it finds a local file. Simple fix below.

This enables --enable-gold flag to be used (doesn't compile yet though).
The gold linker promises up to five times faster linking than ld, it is also possible to use link-time optimizations.
* define __STDC_ISO_10646__ to '201103' in order to indicate that
Haiku's wchar_t supports the Universal Character Set (UCS) defined
by the ISO 10646 standard published in March 2011.
Forcibly prevent fixinclude from executing. This prevents the spawning of a
shell process, which would be abandoned due to fixinc crashing.

* replace gmp.info-? in gcc/gmp/doc by gmp.info, since the latter
is the makeinfo target that will otherwise have to be generated
each time gcc4 is built
* add autom4te.cache to svn:ignore

* remove all *.info targets so the gcc2 build system doesn't
try to update them, as that doesn't always work because of
apparent incompatibilities with newer makeinfo versions

It should probably be a command line option as it might be interesting in some cases.
Also added a "Build Failure" at the end if there were failed targets.
