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,
