Subject: Define MPFR_USE_INTMAX_T so that mpfr.h assumes intmax_t is available.
X-Git-Tag: users/hjl/linux/release/2.29.51.0.1^2~10^2~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7505954411a168f5c5b9adec23eac55b1532fbe6;p=thirdparty%2Fbinutils-gdb.git

Define MPFR_USE_INTMAX_T so that mpfr.h assumes intmax_t is available.

mpfr.h uses a non-portable test to guess if intmax_t is available and
if API functions using intmax_t should be exposed.  Define
MPFR_USE_INTMAX_T to override the non-portable test and always expose
these functions.  This fixes the build on platforms where the test
guesses incorrectly.

gdb/ChangeLog:

	* target-float.c [HAVE_LIBMPFR]: Define MPFR_USE_INTMAX_T.
