Nothing helpful yet - so maybe I wasn't clear about the problem.  Attached 
is a small test port Makefile to demonstrate the problem.  The objective 
is to change the CFLAGS setting in there in a way that will result 
in "-addme" being part of the final output of:

   make MCONF=empty clean all
   make MCONF=test1 clean all
   make MCONF=test2 clean all
   make MCONF=test3 clean all

This currently works for empty and test{1,2}, but fails for test3.

This test3 uses a make.conf (passed via MAKE_ARGS= __MAKE_CONF=...) that 
has a

	CFLAGS= -test

line.

Any help appreciated!
