I got Emacs running on an RS/6000 here, using the previous version of the
patches -- thanks very much to everyone who contributed them, by the way! --
and the X and mouse support seems to work fine so far.  Is the definition of
window-system-version the only change w.r.t. X/mouse support?  I worked
around the problem of window-system-version not being defined by modifying
x-mouse.el and term/x-win.el to test for window-system-version being non-nil
before attempting to use the value.  I.e., previously those files had 3 or 4
statements of the form
	(if (= window-system-version 11)
	...
but the variable wasn't defined (which is curious, since it's plainly there
in x11term.c) and so it would complain about comparing nil to an integer.
Changing all statements of that form to
	(if (and window-system-version (= window-system-version 11))
	....
fixed this.

I regret not having the time to investigate the problem with
window-system-version not being set properly, and so cannot offer help.
