I do not understand this. You are saying that __clang__ being defined
and _MSC_VER being defined should always be strict compliance with
variadics turned on but without any VC++ related fixes ? What about the
so-called emulation by clang of the non-standard VC++ preprocessor ? it
does not work of course but you still want me to ignore it completely
and consider that clang targeting VC++ ( aka clang-cl in clang for
Windows ) uses a C++ standard preprocessor ?
