I sent this to the maintainer a couple weeks ago with no response, so
I'm resending it here.
The emacs configure script mistakenly thinks that openbsd-*-hppa* is
68k instead of PA-RISC, and since 68k has been deprecated in Emacs 22,
the build fails with a deprecation warning. The following simple
patch corrects this, the configure.in patch has already been
accepted upstream.
