#2 Fix extra qualification error with gcc 4.1.0

[Ken Prox]

When compiling on Fedora core 5, using gcc version:

gcc (GCC) 4.1.0 20060304 (Red Hat 4.1.0-3)
Copyright (C) 2006 Free Software Foundation, Inc.

The following error occurs:

../../include/xclass/OXListTree.h:143: error: extra
qualification ‘OXListTree::’ on member ‘_FindItem

The included patch adds the -fpermissive option to the
CCFLAGS, compiles and works OK on FC5.
