It does not.  We do not support running the PGTK build on X (the
selection code doesn't work on X, for example), and there is no way to
"touch" the user time on that platform without relying on X11-specific
code.  At present, it's not even possible to include gdk/gdkx.h there
due to typedef conflicts with dispextern.h.

After thinking a bit, I figure that a better way to solve the problem
would be to document that window managers don't always respect
x-focus-frame, and to add a force parameter which makes it query for the
current server time and set it as the user time, thus making focus
setting more reliable.

Thanks.
