* lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'

Browse Source 
to `yes' instead of `int$1_t' if the type is found, for more
consistent configure output (where $1 is the number of bits).
(_AC_TYPE_UINT): Likewise for `uint$1_t'.
Suggested by Bruno Haible.

* lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
with system headers. Report by Bruno Haible.
