New Revision: 43282
URL: http://svn.boost.org/trac/boost/changeset/43282

Log:
Made the msvc toolset always explicitly enable or disable rtti support based on the <rtti> feature value instead of only setting it if <rtti>on and depending on it being disabled by default. The original behaviour did not work well with msvc 8.0 for which there was not way to disable rtti support as that compiler enables rtti support by default.
