Well, depends. Probably a bug in Sage, but it always used to be that way.
(And I suggested adding `-fno-strict-aliasing` in `setup.py` loooooong
time ago, but nobody bothered. Only Cython-generated code requires this.)

what it's called).
> I disagree with this conclusion, since over-riding `CFLAGS` also removes
other mandatory flags, like `-fno-strict-aliasing`. So you're basically
saying that my patch breaks something which is already broken.
Nope. It ''further'' breaks building extension modules, IMHO without any
gain.
(Btw., exporting `CFLAGS=""` is sufficient.)
