GMP 4.2 building 64 bit shared libraries on Darwin

[Jack Howarth]

   The new GMP 4.2 release now builds 64 bit shared libraries
on MacOS X 10.4. This is going to be a big problem for gfortran
users since gfortran links in gmp and mpfr. The current builds
of GMP 4.2 would require both libmpfr and gfortran to be
built as 64 bit binaries. What this the intention of the
GMP developers for the 4.2 release?
