Cannot bootstrap on NetBSD/cobalt


From: Kenichi Handa
Subject: Cannot bootstrap on NetBSD/cobalt
Date: Mon, 06 Mar 2006 17:18:16 +0900
User-agent: SEMI/1.14.3 (Ushinoya) FLIM/1.14.2 (Yagi-Nishiguchi) APEL/10.2 Emacs/22.0.50 (i686-pc-linux-gnu) MULE/5.0 (SAKAKI)

I got this bug report (translated by me from the original
Japanese).  As I don't have NetBSD nor mips machine, I can't
work on it.

----------------------------------------------------------------------
When we build Emacs on "Cobalt Cache RaQ2" with
NetBSD/cobalt or on hpcmips with NetBSD-3.99.11 (no X11),
temacs can't be build correctly.

/usr/lib/crt{i,begin,end,n}.o are not linked with temacs.
It seems the culprit is that START_FILES and LIB_STANDARD
defined in src/s/netbsd.h are overridden by src/m/mips.h and
src/m/pmax.h.

With the attached patch, it is confirmed that the Emacs
built on hpcmips/NetBSD at least starts up.  But, the patch
may cause a problem for the other OS (especially OpenBSD and
older NetBSD).
