Re: [boost] [variant] RTTI

Michael,

This is used by variant to support the variant::type method.
Otherwise, as Benoit explained, it is not used.

I know in the past there had been discussion about defining a
BOOST_NO_RTTI macro, but I don't think this went anywhere...? If there
were such a macro, the variant implementation could be changed to
conditionally compile the variant::type method, etc.
