g77 legacy features in gfortran

[Jack Howarth]

    We have had a request to update the g77 package to
provide MacIntel support in the fink packages on Mac OS X.
I am told that the following issues require the continued
existence of a g77 package in fink...

1) support for multiple entry points in subprocedures (sad but necessary
for legacy code);
2) EQUIVALENCE in COMMON;
3) stabs or dwarf debugging information for COMMON and EQUIVALENCE
symbols;
4) source input compatibility (tab handling and free-form continuation).

Are this all still accurate for gfortran in gcc trunk? I assume the
third may be true, but am wondering about the others.
      Thanks in advance for any clarifications.
