So I tried doing that by adding -Werror to longfin's CFLAGS environment,
and it crashed and burned in configure. The most obvious problem is
that we didn't bother to supply a prototype for does_int64_work() in
the probes for 64-bit ints. However, even after fixing that, configure
produces totally bollixed output because -Werror breaks many of its
built-in tests. We could fix the int64 tests but we have no good way of
fixing the built-in tests.
AFAICS, if you want to build with -Werror, you have to configure without
that and then inject it afterwards. I wonder how people who use -Werror
are handling that. Is it possible to do at all in a buildfarm critter?
