My answer is NOT related directly to your question , please forgive me .


I am using G95 ( from www.g95.org which is in the packages of FreeBSD ) in
Windows and Linux , and I like it very much because it generates very good
code , especially if the stack traces are enabled in command line , on run
time errors it is giving nearly exact source line of the error point with a
list of called subroutines chain  . Since the G95 is generated from the same
sources for the FreeBSD , I think there is no difference between platform
related compilers .

Another point is ( if your source files have .FOR extension , it is using
Fortran 77 , if it is .F90 , it is using the Fortran 95 ( be careful about
cases of letters ) . For such points , please read its manual . If any
Fortran 77 source file has .F90 extension , it will produce a lot of errors
because Fortran 77 is fixed line format based , Fortran 90 or 95 is free
line format based .

Thank you very much .
