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

If all compilers would behave behave the same way it wouldn't an issue.  But 
having to maintain something just for gfortran is just inconvenient.

ifort and sunf95 both take 
  -fpp
to preprocess a source file while gfortran wants 
 -cpp
ifort and sunf95 both use the standard cpp 
  #define TO_STR(EXPR) #EXPR
while gfortran wants
  #define TO_STR(EXPR) "EXPR"

No show stoppers at all, but inconvenient.
