Arent the xBSD X libraries under the two-clause BSD licence these
days? That licence is GPL-compatible.

The point is that the LGPL's *general* rule about derived works is
more lax than that of the GPL: The LGPL does not require the entire
derived work to be licenced under GPL, just that the user can plug in
new versions of the LGPL-covered part. Thus the "OS-component"
exception is typically not invoked at all in these cases.
