Cbc/trunk used to point to Cgl/stable - now points to Cgl/trunk

that seems to fix problem

Thank you for fixing the bug, I have tested it and it works when using Cgl/trunk.

I am reopening the report as I believe the subversion property svn:externals on Cbc/trunk also should be updated as a part of the fix.
