[lldb-dev] Enabling warnings as errors

There are alot of compilers, but only a small number that we support
building with. And really, the burden would only be on making sure that
the compiler you personally build with builds warning free (which,
unfortunately, even that doesn't always happen). If someone checks
something in on Mac that introduces warnings on Windows with MSVC, then a
Windows person would need to fix it, but I don't think that's too big of a
deal (well, I don't mind anyway). The difference is just that "strive"
would become "require". Sometimes you can't fix warnings for whatever
reason, but you could still disable them in that case.
I guess in an ideal world I would agree with you, that we should strive to
keep warnings down to as low a level as possible. But in practice I think
it's too easy to ignore them, and so people do.
