I wonder if we ought to make configure warn if it sees -Werror in CFLAGS -
this is far from the first time somebody stumbling with -Werror. Including a
few quite senior hackers, if I recall correctly. We could also just filter it
temporarily and put it back at the end of configure.
I don't think there's great way of making the autoconf buildsystem use -Werror
continually, today. IIRC the best way is to use Makefile.custom.
