That draft is no longer current, see https://wg21.link/p0935r0

Nothing changed, you just needed a rebuild. Next time please do a clean build
and double check before reporting a bug. Incremental builds are not supported
on trunk, if you live on the bleeding edge you need to deal with it. Even "make
clean" isn't always enough, you might need a completely new build in an empty
directory.
Building in the source directory is also not supported, see
https://gcc.gnu.org/wiki/FAQ#configure (building in a separate directory has
the advantage that you can just remove the entire build dir and start again,
and the sources are unaffected because they're in a different directory).
