Subject: patch: emacs-24.0.91 FTBFS on GNU/Hurd
Date: Mon, 31 Oct 2011 23:54:31 +0100

Hello,

Interesting to see that emacs-24.1 is on its way with many new features.
When trying to compile the latest pre-release under GNU/Hurd, the build
fails due to a missing definition in src/gnu.h. Inlined is a patch to
add the proper definition of GC_MARK_STACK (as on many of the other
architectures). Otherwise the global variable: static Lisp_Object Vdead;
is undefined on line 6264: if (!EQ (obj, Vdead)) in function
which_symbols().

Thanks!

Sounds good.  I did that as bzr 106331
and am marking this bug as done.
