Okay, so let's have BOOST_NO_RTTI defined when the compiler/environment 
does not support RTTI, and we can use it to turn off use of RTTI in 
some Boost components :)

But Peter is right, there are macros here... perhaps BOOST_NO_RTTI and 
BOOST_NO_DYNAMIC_RTTI, with the former implying the latter.
