I don't.
I haven't noticed anyone else addressing this question,
which I think is a good one.
I don't think doing any of both is a good idea. Authors of the affected
programs should adjust their makefiles instead - after all, the much more
often reported problems are with -fstrict-aliasing, and this one also doesn't
get any special treatment by autoconf. Even though -fno-strict-aliasing -fwrapv
would be a valid, more forgiving default. Also as ever, -O2 is what get's
the most testing, so you are going to more likely run into compiler bugs
with -fwrapv.
