Do you want to say f2c is light package, and g95 is heavy package?

I have thought when USE_LANGUAGES=fortran, g95 should be used,
and when USE_LANGUAGES=fortran77, f2c should be used.
But according to joerg@, fortran77 and fortran cannot coexist as
pkgsrc compiler, because ABI incompatibility. My understanding is right?
If fortran77 and fortran cannot coexist as pkgsrc compiler,
when f2c is default fortran compiler, USE_LANGUAGES=fortran should not
By the way,
I have thought fc2 is only supports fortran77,
but in pkgsrc/mk/compiler/f2c.mk,
LANGUAGES.f2c=fortran fortran77 is defined.
Is this correct?
