Aha. I knew `CC` was "intentionally" unset in GAP's `spkg-install` for a
long time (which was annoying anyway), but '''now''' I still get:
{{{

}}}
So if there's been an issue with `CC` and `CXX` set, it might have been
'''fixed upstream''' (I believe so), but it '''isn't fixed in Sage'''.
[The problem here simply is that the "default" `gcc`, which is 4.4.3,
doesn't understand some of the options I pass in `CFLAGS`. GCC 4.6.3,
specified in `CC`, of course ''does'' understand them.]
