NetBSD, and I'm sure many other popular freely available operating
systems, come with GNU FORTRAN:

$ f77 --version
GNU Fortran 0.5.24-19981002

For more version information on components of the GNU Fortran
compilation system, especially useful when reporting bugs,
type the command `g77 --verbose'.

GNU Fortran comes with NO WARRANTY, to the extent permitted by law.

or type the command `info -f g77 Copying'.


The GNU Fortran Language
************************

   GNU Fortran supports a variety of extensions to, and dialects of,
the Fortran language.  Its primary base is the ANSI FORTRAN 77
standard, currently available on the network at
`http://www.fortran.com/fortran/F77_std/rjcnf0001.html' or as
monolithic text at
`http://www.fortran.com/fortran/F77_std/f77_std.html'.  It offers some
extensions that are popular among users of UNIX `f77' and `f2c'
compilers, some that are popular among users of other compilers (such
as Digital products), some that are popular among users of the newer
Fortran 90 standard, and some that are introduced by GNU Fortran.
