Modified Files:
wxWindows/setup.h_vms wxWindows/include/wx/filefn.h
wxWindows/include/wx/filename.h
wxWindows/src/common/descrip.mms
wxWindows/src/common/filename.cpp
Updates for OpenVMS,
-Updated copmpile support for new files/features
-First version of OpenVMS file support (wxPATH_VMS).
(will need a lot of testing on OpenVMS systems)
