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

gfortran's preprocessor uses traditional C preprocessing rules, which 
differ from what was standardized in C90 in regards to token pasting and 
stringification.  There may be a command line option to change this 
behavior (I don't know), and it may make sense to revise that decision 
if all other compilers behave differently.
