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!
