Or Intel will sell you their Fortran compiler. I guess you can get academic or open source license deals too, but it ends up feeling like you need a law degree to determine whether or not you can redistribute the results. Kind of annoying that Intel's Fortran compiler on Windows is the only commonly-used one that doesn't at least allow you to ask for gfortran-compatible mangling. Hopefully if the PGI LLVM Fortran front-end ever gets released it'll be another option (fingers crossed that it uses gfortran compatible mangling so life is simpler).
