 For example, when compiling Fortran subroutines within modules, the
exported name on my system (gcc on Ubuntu of some flavour) becomes
__subroutinename_MOD_modulename. Calling .C on that works, I couldn't
find any variation on that using underscores or not that worked with
.Fortran. The help for .Fortran has a few words on this.

 Stick to FORTRAN-IV or that new kid on the block, FORTRAN77 :)
