It's only supported by gcc 11+ and clang 11+ (both from ~2021) because it was a suggested C2x extension. It's been accepted in C23 so other compilers will eventually support it, but I wouldn't hold my breath regarding when that happens.

Ah, of course, in C mode it's different. (I nearly always use C++ mode, where at least GCC 10 happily takes it.)
