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.
