Re: JIGS SimpleApp example

[Mathew McBride]

GWorkspace and a few other apps (Waiho) are working fine.

It looks like objc-load is sanity checking to see if any modules  being 
loaded do not have undefined symbols (bad for us, gnustep-base has 
tonnes of them). Removing that check gets errors about the lack of 
GSBackend in gnustep-back (ouch).

On the other hand, ObjC->Java is working fine.
