I just submitted the following as a bug against emacs-19.30...  With
the ECOFF header changes I committed today, and the following diffs,
Emacs 19.30 works great on NetBSD/Alpha, including unexec support.

Hopefully, the next release will compile out of the box.

Subject: Emacs (19.30) doesn't include support for NetBSD/Alpha
cc: cgd+@cs.cmu.edu
From: cgd+@cs.cmu.edu

In GNU Emacs 19.30.2 (alpha-unknown-netbsd1.1B) of Mon May  6 1996 on bunnahabhain.pdl.cs.cmu.edu

Emacs 19.30 doesn't include support for NetBSD/Alpha.  I've written
the code to do it, and have included diffs below.  Since this message
was sent from emacs running on NetBSD/Alpha, i figure they work OK.  8-)
