I think it's a defect in both. Boost should drop the overloaded vararg 
is_function_ptr_tester specializations with non-standard calling 
conventions as they are never used. When MSVC encounters a vararg 
function with stdcall/fastcall it silently converts it to cdecl. Though 
for compatibility with (broken) MSVC code Clang should match that 
behavior if desired.
