But given the discussions Joseph started, the above patch changes it such t= hat it only will be recognized as an extension outside of string/character lite= rals if it starts with \N{ rather than just \N and only in the non-standard modes (-std=3Dgnu*) except for -std=3Dc++2{3,b}. So \NARG will be handled as before without any diagnostics...=
