gfortran performance

I just did a comparison of the netlib 1000s.f benchmark compiled and run 
using g77 and gfortran.  gfortran outperformed g77 with -O2 
march=pentium4.  I think that this is a good indicator that all the 
efforts that you are making is paying off.

I am finding that for my own code using f90 compiles and runs fine.  I 
generally don't use some of the more obscure features.  Even those will 
eventually be cleaned up.  We are gaining the benefit of advances in the 
gcc backend as well.

Just a positive note.
