	It's kind of kludgey (sp?), but if you _know_ that the only change to
the header was the addition of a prototype that is currently unused in any other
module, you could *touch* each of the other modules (.c and .obj).  Then make
should leave them alone.  I have sometimes been forced to do this when I have
added a (not currently used, but will be soon) #define to a header file that
would otherwise cause 30 modules to recompile.

	It's a terrible hack, I know, but it beats waiting xx minutes for a
completely unnecessary recompile.  (Of course, if you have no easy way of
updating the modification time on the file, all bets are off - Oh well :-).

	If there is a better way, I don't know what it is, BUT I SURE WOULD
LIKE TO!!!
