Yes and no.  As long as all I/O and the main program is contained in 
gfortran-compiled code, and as long as you use gfortran for the linking 
stage, everything should work.  In some corner cases you may need to 
provide the -ff2c flag, and perhaps the -fsecond-underscore flag.

Every other combination will probably fail.
