The "-Wstrict-overflow=5" warning seems useful, as it's easy to get this
wrong. I think C really should have "-fwrapv" behavior, but the reality
is that we need to be careful about signed overflow. The warning helps
with that, and luckily there are only a few places that require fixes.
Note that libparser and mini-gmp.c cannot build with "-Wstrict-overflow=5".
Maybe there are other warnings, as it depends on the optimization level
and the compiler. This works for my gcc and -O3.
