[src/mpfr-intmax.h] Define mpfr_intmax_t as being the largest
signed integer type available for the MPFR build. It will be
useful for the formatted output functions (src/vasprintf.c) to
handle the 'n' format specifier, assuming that the value may
be larger than INT_MAX, which is possible assuming that the
C standard has a defect in the corresponding specification:
