The objc/runtime.h file was added only in recent versions of gcc (not sure 
which one exactly). So assuming that the gcc version on NetBSD is old enough 
they are right. That said, the configure script checks for the presence of 
objc/runtime.h for exactly this reason, so a missing objc/runtime.h should not 
cause problems. Can you post the full config.log file here?
