As Oliver found out, the libstdc++.r4 code is available at GeekGadgets, 
too, so it looks like we've almost solved the issue (he is currently 
trying to get it to run with our libio version...)

Can we solve this? Regression testing is not that senseless :)
OTOH there is no pressure, we could run the tests later, too (and fix 
any issues then).

There you go :)
I've changed libbeadapter.so to provide the new Haiku syscalls, and 
changed all direct syscall uses to the new ones. The build system now 
builds libbe.so as a stand-alone (and actually working) object.

Okay.

Definitely!

Still need to :)

I've done it this way, now - have a look if you like it :-)
