I tend to agree with Darin.  We have had relatively few issues with g77.
We have had problems with some versions of g95.  Basically some worked,
some did not.

gfortran releases after version 4.1 are not compatible with NONMEM 
because it is a Fortran 95 compiler and NONMEM is written to conform 
with the Fortran 77 standard. The gfortran developers claim that "most" 
Fortran 77 code "should" work with minimal or no code modifications but 
this didn't prove to be the case. I tried getting NONMEM to build with 
gfortran 4.2.x for the better part of a day using a myriad of 
compatibility options but it was to no avail, at which point I switched 
to GNU Fortran g77 3.3.5 and have had no issues what so ever.

If anyone has had success building NONMEM with recent releases gfortran 
I'd be very interested in knowing which version and the options used.
