I suggest removing the "#ifdef __GNU__" here and in its other
three uses in the patch, as functions like as geteuid() can fail on
a few non-GNU systems too. See:

For this particular application (the 'id' program) I doubt whether
it's worth our time to configure this stuff at compile-time,
and that it's fine to do a run-time check on all platforms.
