This is not really new, you could use it since VC4.2 (Microsoft ~1995)=0D
The only thing was you had to include <iso646.h>:=0D

that these digraphs and trigraphs were both created to help people with

part of the standard, MINGW is the only compiler i have seen that accepts
these keywords so far but naturally i am expecting to see them recognised
