[Bug bootstrap/45326] New: gmp's use of C99 keeps breaking my compiles, suggest set autoconf variables to avoid inttypes/stdint

["jay dot krell at cornell dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

I seem to keep running into inttypes.h/stdint.h that aren't quite adequate,
esp. for gmp. For example, in mpfr:


https://gforge.inria.fr/scm/viewvc.php/trunk/get_uj.c?view=log&root=mpfr&pathrev=7083#rev7082


Anyway, I suggest this to reduce the problem:

 @endif gmp

Slightly tested.
I tried setting the ac_* variables around the entire gcc configure but that
broke's libiberty's use of intptr_t.
