What seems to be the problem?  If you are Unix user, and used some
C compiler in the past, then you know how to call these:

	gcc -c source.c    -- to compile source.c into source.o
	gcc -o myprog myprog.c sub1.c sub2.c ...
			   -- to produce executable program myprog
	gcc -o myprog myprog.o sub1.o sub2.o ...
			   -- same, but after they are already compiled

Two main things in which DJGPP differs from a Unix GCC usage:

	1) To produce an .exe file, you should do this:

		coff2exe myprog

	   where myprog is the result of the linker step as above.
	   This will produce myprog.exe which you can run.
	   Alternatively, you can run myprog directly, like this:

		go32 myprog [args...]

	   Go32.exe is in your bin subdirectory of the main DJGPP
	   directory.

	2) If you use PC-specific library routines like cprintf()
	   and inportb(), put -lpc at the end of the link command line,
	   like this:

		gcc -o myprog myprog.o sub1.o ... -lpc

If this doesn't get you off the ground, tell me more about what
specifically doesn't work and what error messages do you see.
