[boost] [svn][function] missing include is_void.hpp?

The changeset  43884 added some code using is_void, but it seems
is_void.hpp is not included somewhere by Boost.Function. I think
boost/function/detail/prologue.hpp should include it, right?

I post this because today's svn cannot compile (with VC9).
