Subject: [PATCH] Some versions of X, have the Shape extension, but apparently
 not "ShapeInput" (Fixes bug #4662)

the sawfish window manager has ifdefs for this sort of situation.
I followed suit, and #ifdef'd it, and it now works for me.
patch attached.

Slight changes to the patch from danakj@orodu.net for readability
