[boost] MPL/type_traits patches for Sun

I recently spent some time trying to port Boost to Sun's latest
compiler. The bugs I encountered are really somewhat amazing.  For
example, this file doesn't compile:

    template <bool c>
    struct bool_c
    {
        static const bool value = c;
    };

    template <class A>
    struct bigger_than_short
        : bool_c< (sizeof(A) > sizeof(short)) >
    {

    };

    int main()
    {
        bool x = bigger_than_short<long>::value;
    };

In order to work around this bug, I had to make the enclosed local
patch to boost/type_traits/detail/bool_trait_def.hpp. I didn't check
it in because it wasn't absolutely clear to me that it was
legit. Aleksey, please comment:
