Thanks a lot! That really helps!

However, when trying -fobjc-runtime=gnu and NOT using the GNUstep runtime, I get this:

Undefined symbols for architecture x86_64:
  "_objc_msgSend", referenced from:
      _of_application_main in OFApplication.lib.o
      __c_OFApplication__sharedApplication in OFApplication.lib.o

      __i_OFArrayEnumerator__dealloc in OFArray.lib.o
      __i_OFArray_subarray__initWithArray_range_ in OFArray_subarray.lib.o
      ...

These are not present in the GNU runtime, yet they are referenced.

So, we still seem to have the problem that GNU runtime means GNUstep runtime in Clang and is by no means the GNU GCC runtime. I guess this is something David needs to clean up by removing the GNUstep runtime from -fobjc-runtime=gnu and moving it to -fobjc-runtime=gnustep?
