The files are most often named somemodule.h and somemodule.cpp
and somemain.cpp

to refer to these in your sorce use the line:
#include "somemodule.h"

to compile all these in one step you need the make utility which can be
found where you got djgpp.
create one file called "makefile"  no extentions, in the directory with
your source.

here is one of mine from a school project:

bank.exe: bank.o tree.o accounts.o
	gxx -o bank.exe bank.o tree.o accounts.o

bank.o: bank.cpp tree.h accounts.h
	gcc -c bank.cpp

tree.o: tree.cpp tree.h accounts.h
	gcc -c tree.cpp

accounts.o: accounts.cpp accounts.h
	gcc -c accounts.cpp

  ^ this white space indenting these second lines MUST be a single TAB
not padded with spaces.

accounts.* and tree.* were my separate modules and bank.cpp was my main
program.
these are set up like this:

output.file: [dependencies]
	command line

once this is set, at the command line type:

make

this will run the make utility which will check all your dependencies
compiling only what is out of date
and link them. Naturally all command line switches can also be used.

Later!
Dave.
