Sorry, I've accidentally dropped an email about `make -U'.
I think that it's not needed, since the functionality can
easily be achieved by running "make FOO=3D", i.e., assigning
an empty value. Remember that command line variables take
precedence over globals, so the following makefile,
FOO+=3D bar
all:
@echo ${FOO}
when run as ``make FOO=3Dfoo'', will print just ``foo''.
Cheers,
