[cp-patches] [patch] make darwin 'work' with classpath

[Andreas Tobler]

Hi all,

the attached patch changes link behavior of darwin ppc and makes it work 
in reality. For detailed explanation please search the apple developer 
pages.
In short, when building against a .so we have a module which is like an 
extension an not like a shared library as known on ppc linux. It is not 
possible to link against an extension/module/bundle.

It's a longer story and I do not have the breath to expalin every detail 
right now. I'm certainly open to expalin it. With this test I can run 
the mauve tests and co quite successfully. I even can run some simple 
(sometimes bigger) gui apps with it.

Regards,
Andreas

        * configure.ac (LIBVERSION): Check against darwin to set module 'no'
        for it. Modules under darwin are not linkable. See Apple docs.
        * configure: Regenerate
