lchown returns ENOSYS on a 2.0 kernel.  However, there is no
problem with glibc compilation because the numbers didn't change.

Emulation on alpha is also much more painful than the method you
present because the numbers didn't change.  It is just not worth
it, IMO.

Debian should be using 

	ret = lchown(foo, bar);
	if (ret < 0 && errno == ENOSYS)
		ret = chown(foo, bar);

That will work everywhere.
