Won't compile in C++ mode on MSVC

uthash assumes the existence of typeof() when being compiled as C++ - unfortunately MSVC does not implement typeof() and hence it won't compile. Here is a C++ metaprogramming implementation of typeof() for MSVC (taken from http://www.nedproductions.biz/blog/2009/11/09/implementing-typeof-in-microsofts-c-compiler): #if defined(_MSC_VER) && _MSC_VER>=1400 namespace msvc_typeof_impl { /*...

Won't compile on MSVC9 or older compilers
