preprocessor token "#" doesn't work in gfortran as in gcc, intel-fortran or sun-fortran compiler

For the sake of explanation, not adding much to the discussion: gfortran 
strives for compatibility with g77 (the longtime 'standard' Fortran 
compiler).  g77 used traditional preprocessing.  That's why gfortran 
behaves the way it does.  I'm surprised other compilers chose to act 
incompatibly.  Since noone complained so far (as for all I remember), my 
guess is that either the differences simply are not what Fortran users 
care about or people are happy with g77-compatible behavior.
