I found out one way to make it compile. The problem seems to be that
VS 2010 isn't able to instantiate identity in this context:

template<class U>
char_array<sizeof(typename identity<U>::type)>
indirect_sizeof_test(by_reference<U>);

With any of the overloads. There's a workaround just above this to
deal with GCC 3.1 (I think) where it doesn't use identity, but U
directly. I added MSVC with MSC_VER == 1600 and it worked.
