Subject: bug#8395: Compile error with Xcode 4.1 in unexec

Hi -
I've been trying to build emacs-23 branch from bzr using Xcode 4.1 (not, not 4.0.1) with either included compiler. While the patch for bug 8223 resolved one issue that I'm having, I subsequently encounter another error in unexec, found attached below.
I'm happy to help debug this, as 4.1 may not be readily available to all involved - but will require some guidance from someone familiar with the code.
thanks,
/-Will
