You are correct. The 32 bit setup is on a different computer, and there I'm
gcc and gfortran built by equation solution (v4.5.0). (No MSVC, and it works

I was hoping to continue with gcc for 64bit, but understood that msvc was
required. My attempted 64 bit setup is MSVC 2008 Pro for c, and mingw-w64
for the fortran part.

Thank you for the information. I will have to look into options for a
fortran compiler, for now.
