Changes needed to make gmp 4.2.1 build with GCC trunk

[Richard Guenther]

FYI,

GCC 4.3 will change inline semantics to be standard conforming to
C99.  The t-locale.cc test references abort(), so it should include
cstdlib.

If those already are fixed in development sources just ignore this
post.

Thanks,
Richard.
