For the benefit of understanding this issue by those not intimately 
involved in Fortran business:  Most closed-source Fortran compilers 
consisted as two separate executables for about a decade before the 
Fortran 90/95 compiler was "good enough" at the Fortran 77 stuff to be 
the only offering.

We hope to work faster than that, but don't hold your breath.
