Objective-C Runtime Extensions. This directory contains files which slightly extend the standard Objective-C runtime provided with GCC. The most significant change is in the Object class, which adds some methods for allocating and copying objects within "zones". See the NSZone source in the libobjects distribution for more information on zones. The other files include additions to the runtime which are used by libobjcX applications. Applications that use libobjcX must use the Object class provided here rather than the one provided with the standard GCC distribution. This should always be the case since any application should include -lobjcX before -lobjc during linking.
