Re: GNU ObjC runtime bug.

[Nicola Pero <nicola at brainstorm dot co dot uk>]

Please revert this patch immediately from 3.0.

The table of methods which have been loaded is *global* for all classes.
The result of the patch is that once +load is called *once* in a class, it
is never called again in any other class!

In fact, gnustep-base doesn't work with that patch.

I know that before the thing wasn't satisfactory, but at least +load *was*
called.  It's better to restore the previous traditional situation on 3.0,
and we will attempt to figure out how to fix the details on the mainline.  
Trying to fix bugs so near the release is not a good idea.

Here is a testcase which worked before the patch, and fails after the
patch.  Please commit it to the testsuite as load2.m.
