Well, I use g77 for months on my workstation & my PC without special
problems.
It's also possible to mix C and Fortran code with djgpp as long as
the way of parameter passing between fortran & C is correct
(pointers only , hidden argument on characters, etc.).

If the problem is located within the fortran module, then
there are a lot of possible reasons for that error.

 Try to compile your program with the option "-fno-automatic".
   Some Fortran subroutines expect the local variables to be "SAVE"d 
   implicitely between two calls. Without this option, the value
   of each local variable is undefined when the subroutine is
   entered.

 If this isn't the error, check the code for subscript-out-of-range
   errors. To do this I would suggest you to compile the fortran
   modules with f2c only, with the option "-C", and then use gcc.

 If this all won't help you, consider to post the piece of code
   that produces the error to this mailing-list/newsgroup.
