 Emacs fails to compile on 10.7 because of this error:


 {{{
 :info:build nsterm.m:8391:8: error: use of undeclared identifier 'child'
 :info:build   if ([child
 respondsToSelector:@selector(setAccessibilitySubrole:)])
 :info:build        ^

 }}}

 The code looks for a non existing ivar, checking source code, emacs fixed
 it with this commit:

 https://github.com/emacs-
 mirror/emacs/commit/96ec2ac7d0bdb6b1193217b35f7d74d79b7c2033

 we might have a backport patch for it. It does not apply cleanly, but it
 contains the fix for that part.

 Another build issue remains:

 {{{
 nsmenu.m:644:48: error: use of undeclared identifier
 'NSTextAlignmentRight'
     [[[NSTextTab alloc] initWithTextAlignment: NSTextAlignmentRight

 }}}


 And here I am at loss,
 {{{
 NSTextAlignmentRight
 }}}
  is valid, not something recent, what else is missing?
