Hi..


When using tk 8.6 global preferences do not open any more. It complains 
a packing problem. The attached patch fixes it. It is backward 
compatible to at least tk 8.4.

Changelog:

2012-03-19  Roland Schwingel <roland.schwingel@onevision.com>

         * library/globalpref.itb (_build_win): Remove unneeded debug call.
         Fix packing of OK/Apply/Cancel buttons for newer tk versions. Small
         reformatting.

Any comments? Is this ok?

This is the last patch for today and finishes my patch series for gdbtk 
for now. Next I will (most likely) cover libgui.
