Here's the story.

gfortran is the new Fortran front-end; the primary focus of the gfortran
maintainers has been F90/F95 capabilities.  While gfortran does have
some capability to compile F77 code, it is not as complete as the older
g77 compiler.

For that reason Fedora has a g77 compat package which can be used to
provide the older g77 front-end for those who need to compile older
F77 code which uses features not yet available in the gfortran compiler.


compat-gcc-32-g77-<version>


I hope this helps,
