Take typeid(T&) rather than typeid(T). For some some compilers won't

let you get away with typeid(T) when T is an incomplete class
type (that's conforming behavior), but GCC at least will allow
typeid(T&) -- also disallowed by the standard when T is incomplete.
If it turns out that EDGs also barf on typeid(T&), we may have more
work to do.

Some warning suppression for MSVC.
