Sorry I haven't incorporated the 2.7.2.2 patches.

Here are some highlights of work done since the last snapshot...

* ObjC runtime version number has been incremented to 8!  This will require
that you recompile your ObjC source code.  The version number was
incremented because
a fundamental objc structure (which is placed within object code) has been
changed thus making previously compiled programs incompatible.

* GCC has been converted to use the Autoconf package.
* ObjC is now a language front-end.
* C++ and ObjC handle their own configuration, using Autoconf.

* Implementation of +load

* Pretty printing of ObjC method names for compilation errors and warnings.

* Programs compiled with the GNU ObjC runtime library can be debugged with
the native GDB on NEXTSTEP systems.

* Numerous bug fixes.

* Reorganization of the thread/mutex implementation so that there is a
clearly defined front-end/back-end interface.

enjoy!
