[Bug libffi/40701] New: [4.5 regression] Many libffi tests fail to compile on Tru64 UNIX

["ro at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Between 20090522 and 20090612, many libffi tests started to fail on
alpha-dec-osf4.0f:

FAIL: libffi.call/closure_fn0.c -O0 -W -Wall (test for excess errors)
Excess errors:
In file included from
/vol/gcc/src/gcc-dist/libffi/testsuite/libffi.call/closure_fn0.c:13:0:
/vol/gcc/src/gcc-dist/libffi/testsuite/libffi.call/ffitest.h:6:22: fatal error:
inttypes.h: No such file or directory
compilation terminated.

WARNING: libffi.call/closure_fn0.c -O0 -W -Wall compilation failed to produce
executable

It is clearly wrong to unconditionally use <inttypes.h>.  One might consider
using <stdint.h> for in-tree use, which is now always provided by GCC, but this
would be wrong for the external libffi either.

alpha-dec-osf5.1b is not that heavily affected, since it has <inttypes.h>, but
that one unfortunately lacks PRIuPTR:

FAIL: libffi.call/cls_align_pointer.c -O0 -W -Wall (test for excess errors)

The definition of PRIuPTR in intl/loadmsgcat.c might be an option here.
