If I apply all currently available patches and than build Mozilla Firefox with
Clang on Mac OS X 10.6, than it stops with the below error. This is
Mac-specific code. You can find the file in question there:
http://hg.mozilla.org/mozilla-central/file/1b14b3b3095d/widget/src/cocoa/nsMenuX.mm#l509

The error is:


/Volumes/Developer/temp/src/mozilla/widget/src/cocoa/nsMenuX.mm:509:23: error: 
      cannot initialize a parameter of type 'id<NSMenuDelegate>' with an lvalue
      of type 'MenuDelegate *'
  [myMenu setDelegate:mMenuDelegate];
                      ^~~~~~~~~~~~~

I've tried to add a preprocessed source. But if I build with --save-temps, than
I get a completely different error in a completely different file.

clang version 2.8 (trunk 109500)
Target: x86_64-apple-darwin10
