Thanks Ken, a collegue also spotted this problem and I have the code resource
working in my shared library.
It's good to hear that Metrowerks is working on Multi-segment shared libraries.
I hope they fix the problem
with supporting globals as well. It would also be nice if the linker had the
option of optimizing the order of the
objects to limit the number of fixups required for jumps > 32k.

Sorry, I forgot to mention that you need to explicitly open up the
shared library DB, since it's not normally opened when the library is
running. You can stash the DB information when your shared library
gets loaded (your routine is called to return the ptr to the dispatch
table).

Take a look at the PRC with any hex file editor...you should see the
'plug' resource type in the resource entry list following the header.
If not, then you've got a second problem, otherwise I think it's just
the issue of the shared lib resource DB not being opened.

I'm currently working on a way to get Metrowerks to support a
multi-segment shared library...stay tuned.
