These fall into two categories:
  (1) Bug fixes (as evidenced by the numerous new test cases vs. 
mainline)
  (2) Support for new Mac OS X (NeXT) runtime features, accessible via 
-fobjc-exceptions, -fno-nil-receivers, -fzero-link and 
-freplace-objc-classes,
      all of which have already been documented in gcc/doc/invoke.texi. 
 Test cases are included (and made Darwin-specific when appropriate).

I believe that Andreas Jaeger has already prepared an ISO-fying patch 
for Objective-C, and Stan is currently working on putting this into the 
objc-improvmenets-branch.

Please do file a Bugzilla.  Better yet, when the merge to mainline is 
complete, you can have a go at fixing this ICE, along with your 'Class 
<Protocol>' work! :-)
