This is quite long compared to the length of your usual entries.  It
is fine, just would be good to shorten it a bit.

Would it work to say 

 ...will have support for <a href="gcc-4.6/changes.html#objective-c">many
 new Objective-C features</a> and a new GNU Objective-C runtime API.

?

In the second sentence how about omitting "work" and "helpful", especially
the latter appears redundant. ;-)  And I think "support" is sufficient,
we don't need "support and review" here.
