compiling f77 code with gfortran

is it possible to compile f77 code with gfortran?? g77 does it nicely,
gfortran complains.... fatal error: gfc_todo: Not Implemented: arrays
of strings

Yes, as gfortran is meant to replace g77 in the next gcc release.

That being said, you're using a pretty old gcc snapshot. Try with
something remotedly current and see if your problem still persists.

As Janne stated this porblem has been fixed. The actual change, I
believe, went into the gfortran source tree on 2004-04-05. AFAIK,
there are only a few problems with compiling Fortran 77 code. These
include ENTRY and non-integral do-loop iterators.
