[Bug c++/86288] Recognize __gnu and/or __gnu__ as attribute-namespace
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86288 --- Comment #5 from Jonathan Wakely --- Clang has now implemented this as a special case, only recognizing "__gnu__" as a synonym for the "gnu" attribute-namespace. That's fine for libstdc++'s purposes, as I don't expect we'll start using any other vendor attributes. EDG have also been told about this, so compilers based on their front end should also be able to recognize [[__gnu__::__blah__]] at some point.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86288 --- Comment #4 from Jonathan Wakely --- I think Jakub's patch does only allow __gnu__, using the same canonicalization for attribute-namespaces as for attributes.
