The reason why we do this with explicit #ifs that test for a compiler brand, not in an "Autoconfish way", is that we use the result in .h files that should be installable
That makes sense for the definition of _Noreturn in build-aux/snippet/_Noreturn.h, since that file is copied into installable .h files. But it makes less sense for the common Autoconf situation where _Noreturn is defined in <config.h>; such definitions are not intended to be copied into installable .h files, and it might make sense for Autoconf to support that.
