[fpc-pascal] Nonfunctional debugger on OS X

[Paul Davidson]

Using XCode as well.  It would be good idea to upgrade your compiler to 
1.9.6.  Go to directory containing fpc dir and:

   cvs -z 3 -d :pserver:cvs at cvs.freepascal.org:/FPC/CVS checkout -r 
RELEASE_1_9_6

Build instructions are at 
http://www.surtec.com/~rj/Xcode-FreePascal/#FPC/CVS-Quickstart

As far as variables are concerned, you can typically only see local 
vars.  Never been able to see string in meaningful way.

You may also wish to re-install the fpc XCode files
