In fact, djgpp's libc makefiles tell gcc that the first case is an
*error*.  Not only must your functions be fully declared, but you must
have provided a full prototype declaration before you can either use
or define a function.  The net result is that nothing is usable unless
it's in the header files.

Check out the gcc options we use:

	-Wall
	-Werror
	-Wbad-function-cast
	-Wcast-qual
	-Wmissing-declarations
	-Wmissing-prototypes
	-Wpointer-arith
	-Wshadow
	-Wstrict-prototypes
	-Wtraditional
	-Wwrite-strings
