#12944: wchar_t conflict for common_factor_rt.hpp in visual studio
------------------------------+-------------------------

------------------------------+-------------------------
 When attempting to use `common_factor.hpp` I ran into an error where
 `gcd_traits<>` had multiple explicit specializations for `unsigned short`.
 Upon further inspection I realised the vc runtime defines `wchar_t` as
 `typdef unsigned short wchar_t` when the option  `-Zc:wchar_t (wchar_t Is
 Native Type)` is switched off. I had to patch the `common_factor.hpp`
 header in order to use this (since I do not want `wchar_t` to be a built-
 in type). Is there any other way around this? Am I misusing this
 interface?
