Heh, whoops, no ignore that, sorry.  I thought I was doing 'bar.c', but

bar.h #include's zzz.h, but NOT bar.h itself. :)  No recursion.  Sorry for
the typo...

Okay, so Rod's idea for a Makefile variable seems best, since there will
be .h files that include other .h's, and are themselves included by other
.c files...

Heh, in the environment I'm coding for, there ARE no "<>" includes.
