For two separate executables:

  http://www.gnu.org/manual/automake/html_node/automake_32.html#SEC32

Otherwise, if you are referring to object code:

  mumble-flag.o : mumble-flag.c
  mumble-flag.c : mumble.c
	( echo '#define NO_PAGE_CACHE 1' ; \
	  echo '#include "mumble.c"' ) > $@

crude but effective.

Say, Tom, is there a FAQ for this?  I don't see a faq
