Milestone:  Boost 1.42.0             |   Component:  any

 Given the following structure:

 struct B {};
 typedef B type_;
 struct A {
   type_ name;
 };

 BOOST_HAS_MEMBER_DATA(type_, name)


 If type_ is B result is always false. B* works, as well as integral types.
 I don't know why it doesn't work because if you try to instantiate a
 template of given type (eg template <type_ A::*> struct type{};
 type<&A::name>*; there is no compile-error).
 Note: I do not use the typedef shortcut, it is just for exemplary
 purposes, but substituting the type itself doesn't work either.
