Re: [PATCH] Part 2 of Objective-C support

[Andrew Cagney <ac131313@ges.redhat.com>]

Michael,

I'm reverting this change.  It modifies a lot of files, many of which 
are maintained by people other than you and I don't think it falls into 
the ``obvious'' category.  Can you please break these changes down into 
obvious (eg language_objc enum in defs.h) and not so obvious so people 
can at least get a change to digest this.

Andrew
