RE: NONMEM and g77

I've been able to compile and run NONMEM VI version 2.0 using nmqual-6.3.3
and gfortran 4.3, both on Windows and on Linux. I had to make the following

On Windows, edit changes.g77.nm6.xml:
  change CONOUT$ to a filename such as NMOUTPUT

On Linux, edit changes.nix.nm6.xml:
  change the second /dev/null to /dev/tty and the third /dev/null to JUNK

I used the MinGW version of the gcc compilers on Windows and the version of
gcc that ships with Fedora 10 on Linux.

Ignore the huge number of warning messages the compiler spits out. When I
test using, I get the same output as with g77 3.4.5 and 3.4.6.

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.
