[boost] FIX #2 for type_traits (not MPL)

From: Markus Schöpflin (markus.schoepflin_at_[hidden])

Ok, here is the rest of the patches for type_traits I have so far. The 
basic problem is, IBM's vacpp 5 can't do this:

template <bool b> struct foo
{
     static const bool v = b;
};

template <bool b> struct bar
{
     static const bool v1 = b;
     static const bool v2 = foo<v1>::v;
};

It works if you replace foo<v1>::v with foo<b>::v.
