Hi Jeffrey
I read all the mails you sent me and had a serious look at my g77 port.
Yes, it did things wrong because the gcc frontend gets patched to
know about the new Fortran rules, to which g77 is just an interface -
it merely adds the -lf2c -lm libraries.
Here is a new g77 port. It overwrites /usr/bin/{cc,gcc} and installs
f771 in /usr/libexec. Be careful. It's old style although the pre-build
and pre-install targets are gone now.
Please have a close look at it and tell me if it's OK now.
Nils
