yes, exactly, and there's no mature GNU fortran 90 or even 95,
yet.  I've recently read about a "g95" {GNU Fortran 95} development
effort, but haven't taken the time to find out how far they are.

The f2c translator has been supporting some (minor) 
f90 extensions; you might investigate further there.

My consequence: 
   Encourage people using C (or C++ if it really makes sense),
   instead.  
But I know this is no real option for some in the
Numerical-Analysis Community, unfortunately.
