Right you are. And yeah, us moving on to gcc-14 as a minimum version
is not imminent.

Still, while we can't force it, lots of distros are on gcc-15, so
while we'd have the _Generic() macro as a fallback for older versions,
at least most developers would hopefully get the nice clean modern
__typeof_unqual__ thing...
