David removed a pile of legacy headers from libobjc2 last week. And
since there is no thr.h in libobjc2 anymore, base is picking up the
header from gcc's libobjc and gets a bit confused. There is a bit of
refactoring to be done to get libobjc2 and gnustep-base in sync again.
E.g. all includes of objc.h need to be changed to runtime.h. That will
probably also break a lot a of legacy stuff like the old NeXTStep typed
streams. I'm well willing to help with that, after GSoC that is, because
I'm rather busy with DBusKit at the moment…

Cheers,
