 From your description, this appears to be gnustep-make doing the 
correct thing (-DGNUSTEP_RUNTIME=1 means the new runtim,e is in use), 
and the issue would be in the 'subsequent code'

I suppose your problem might be that you are using the more recent 2.2 
ABI but the default is specifying the 2.0 ABI?

You can override the default using --with-runtime-abi configuration option.
