Yes, for g95[2] we already have --fcompiler=g95. I choosed 
--fcompiler=gnu95 to be similar to --fcompiler=gnu as they are 
closely related by the gcc project.

As I understand from gfortran man pages, gfortran will replace g77 in 
future, and so, in future  --fcompiler=gnu should look for gfortran as 
well. For now we need to keep g77 and gfortran support separate as g77-3.4 
is the recommended Fortran compiler by the gcc developers.

So, I would still prefer gnu95 name over gfortran.
