I just tried to compile the following

#include <boost/exception_ptr.hpp>
void f() {}

msvc 10 complains,
1>c:\boost\trunk\boost\smart_ptr\detail\sp_convertible.hpp(48): error

This appears to be because type_info is defined in the global namespace,
so ADL for boost::error_info<boost::tag_original_exception_type, const
type_info *>
picks up the global f.  I don't have a fix for this yet.
