[boost] Support for disabled RTTI

Would it be useful (or correct) to add the following to config/compiler/visualc.hpp:

//
// check for RTTI support:
#ifndef _CPPRTTI
#  define BOOST_NO_TYPEID
#endif

(eg around line 106, after the test for exceptions)
?

I'm using MSVC 7.1 (SP1) with STLport 5.1.5 (latest)

- With the new Boost.Exception I get a drizzle of C4541 warnings.
I don't want to force BOOST_NO_TYPEID in config/user.hpp because
some projects do have RTTI.
