I think it should be possible to just do:

	gcc -o myprog.exe *.c

The usual way is to first compile all the separate .c files like this:

	gcc -c file1.c
	gcc -c file2.c
	gcc -c file3.c

then link the resulting objectfiles together like this:

	gcc -o myprog.exe file1.o file2.o file3.o

becouse this means you don't need to recompile all files each time, only
the files you've changed. (create a Makefile and use make)
