I have long since fixed the "$(shell pwd)" in my makefile, but I still get 
it complaining
about '%' rules being a GNU make extension.  I added "-Wno-portability" to 
CFLAGS & CXXFLAGS, but
that did not change anything.  What do I add -Wno-portability to?
How could I change this rule to not be a % rule?
