[Bug-gnubg] Bug Report - Systems with GTK but no DISPLAY env var

[Michael Petch]

Howdy All,

In my quest to clean up the MAC OSX build I pulled out the latest
sources (.14-2-devel) and have this Patch. The problem is that if you
run gnubg with GTK enabled but DISPLAY unset the command line version of
gnubg segfaults. 

The problem is that fX is set to whether GTK is available (If USE_GTK is
true). There is a section that is #if/#else'd with a check for the
environment variable that does not occur if you use GTK. The check
should occur if GTK is in use or not.

This problem exists on Linux/OSX (Wasn't MAC specific). After fixing
that - checks for fX had to be made in a  couple of other places. See
attached patch
