Kevin Puetz : include: Fix undefined char16_t in C11.

Module: wine Branch: master Commit: d45b3d4fdd7cbcfdba70c327ab90976a3b658da2 URL: https://source.winehq.org/git/wine.git/?a=commit;h=d45b3d4fdd7cbcfdba70c327… Author: Kevin Puetz &lt;PuetzKevinA(a)JohnDeere.com&gt; Date: Thu Sep 24 10:12:09 2020 -0500 include: Fix undefined char16_t in C11. In c++11 char16_t is a distinct fundamental type, but in c11 it is merely a typedef in <uchar.h>. Explicitly mention char16_t only in c++11 (where it is built-in), otherwise define WCHAR as unsigned short (without naming char16_t) and just hope that on C11 this matches u"..." Remove WINE_UNICODE_CHAR16; it is now the default when supported.
