Note: -DUSE_X11=

This should be -DUSE_X11=1 if configure detected X.

Hmm. I'll need to change the Makefile for that. USE_X11 is either 1 or
empty, which isn't easy to test for in a #if directive.

Due to the USE_X11 test failing, Togl thinks it's being compiled for a
Mac.

It is. However, the fact that USE_X11 isn't getting set is the root of
the problem.
