Yes, such a way exists.  It is called ``object file libraries''.  You
put every function on its separate source file and compile it.  You
then put all these .o object files into a library using the `ar'
archive utility which comes with DJGPP:

		ar rvs mylib.a *.o

You then submit the name of that library when you link your programs.
For example:

		gcc -o myprog.exe f1.c f2.c mylib.a

The linker will only link in the functions that your program calls.
