Now, on to the upcoming merge:
The criteria that makes most sense from a users viewpoint is that
tree-ssa could not be merged until gfortran was as good as g77 at
compiling f77. Since mainline gcc has NO f95 users right now, this
criteria would keep gcc from losing existing functionality.
Of course, this is highly unrealistic !!
From the point of view of a complete OS, supplying gfortran *instead
of* g77 is completely unrealistic at the time of 3.5's release.
However, that's not necessary - distributors of complete OS's could use
g77 and gfortran separately (by providing g77 in /opt/bin/g77 for instance).
Proprietary Fortran compilers have existed as two separate binaries for
over a decade to make the transfer from Fortran 77 (plus extensions) to
Fortran 90/95 (and the same extensions or more).
We don't have to beat them on *that*.
Cheers,
