patches to make X11R4 compile on a RS6000

[Elliot_Jaffe at TRANSARC.COM]

I have compiled the X11R4 distribution on the Rs6000.  Of course I only
compiled the clients, since there is no Rs6000 server in the R4 distribution.
I did not bother trying to compile the examples, demos, or doc directories,
so you may need to make additional modifications for them.

One final note, you need to have installed the X11 Xamples directory from the
lpp tape.  The lpp is called /usr/lpp.install/X11devB1.  You need because
IBM has supplied a working cpp since the normal one does not handle
Imakefiles.

One final note: I was able to install the shape extension into the IBM X
server by following the samples in /usr/lpp/X11/Xamples/{extensions,server}.

Good luck,
