most of Boost cannot be built without RTTI. However, most of it can be used without RTTI,
at least in release mode. I've never done this in debug mode.

So what I'm doing is building Boost with
b2.exe --with-... define="BOOST_NO_RTTI"
so that it behaves as if RTTI were disabled except if it's really needed. This doesn't really
feel clean, but it works for me.

Alternatively, you could pass cxxflags="/GR-", but some libraries will just crash then.
