I believe Metrowerks 10 is the first version to contain support for
rvalue references. Since I don't know (and couldn't find online) the
__MWERKS__ constant for Metrowerks 10, I'm changing the __option check
to:

#if __MWERKS__ > 0x3206 && __option(rvalue_refs)
#  define BOOST_HAS_RVALUE_REFS
#endif

If someone knows better, please tell me or update the config in Boost
CVS.

        Cheers,
