Understood and agreed.  Either way, I think a warning (such as I added in the diff) would be welcome -- I do read through the debugging output of ports with which I'm working, and I'd spot such a warning & wonder about it & try to fix it.  The appending was mostly a simple way to get around the limitations of the regexp not working with \" strings to verify that setting CC="${prefix}/bin/gcc-mp-4.4 -m4" worked (it does). - MLD
