 It is well known that GMP doesn't necessarily use the default ABI. The
 reason is that it is generally faster. But I think that's a bad reason
 since this yields compatibility problems with other installed software.

 This shouldn't be necessary: the MPFR configure script uses the GMP CFLAGS
 by default. If for some reason, the MPFR autodetection of CFLAGS doesn't
 work, I'd like to know...
