Replacement Objective-C runtime supporting modern Objective-C features

Replacement for the GNU Objective-C runtime supporting the features of modern dialects of Objective-C for use with GNUstep and other Objective-C programs. This runtime is based on the Etoile Objective-C Runtime, an earlier research prototype, and includes support for non-fragile instance variables, type-dependent dispatch, and object planes. It is fully compatible with the FSF's GCC Objective-C ABI and also implements a new ABI that is supported by Clang and is required for some of the newer features.
