FYI, it's -Wall in AM_INIT_AUTOMAKE from e4c97f1e6 that's doing this.
foreign shuts off the portability warnings.

Since I'm pretty sure there are quite a few parts of the build that
depend on GNU Make, I'd suggest either dropping -Wall or adding
-Wno-portability. I don't see how -Wall is helping here, though.
