Yes. It's the GNU Fortran compiler. Unlike the GNU C compiler, which is
pretty competitive with commercial offerings, the Fortran compiler is a
bit more limited.

It supports just about all the ANSI Fortran 77 standard, but there are a
lot of programs out there that don't agree with the standard.  It's much
worse than C, where declaring main() as void is about the only really
common usage that conflicts with the standard.

The g77 manual has two sections that might be useful: 'Collected Fortran
Wisdom' and "Known Causes of Trouble with GNU Fortran"
