I don't know the history/reason for the split. GMP 4.x
includes essentially mpfr 2.0.1, which was released in
May 2002. There have been 6 newer releases of mpfr
since that time. There are literally hundreds of bug
fixes, new features, and speed improvements. For
gfortran, there is a new mpfr_subnormalize function.
This would allow me to replace a homegrown hack that
Tobi and I developed for dealing with subnormal numbers.
