[boost] typo in is_convertible

From: David Abrahams (dave_at_[hidden])

CVS annotate shows:

1.8          (johnmadd 04-Nov-02): #elif (defined(BOOST_MSVC) && (BOOST_MSVC >= 1310))\
                                                                                ^^^^
I'm changing this to:

        #elif !BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1301)) \

Please advise if I'm making a mistake.

Thanks,
