Hi,

Emacs-23.1 on NetBSD/cobalt (mipsel) 5.0.1 also gets the following
warning message as well as bug#2685 on Debian lenny.

>> Emergency (alloc): Warning: past 85% of memory limit

The following patch (and configure rev 1.326 on HEAD) fixes it:

--- src/m/mips.h.orig	2009-06-21 13:38:20.000000000 +0900
+++ src/m/mips.h

 #endif
 

NetBSD/alpha has the same problem as mentioned in bug#2072, and
the following patch for emacs-23.1 works fine on NetBSD/alpha 5.0:

--- src/m/alpha.h.orig	2009-06-21 13:38:20.000000000 +0900

I guess these DATA_START definitions are for DEC ULTRIX and OSF/1.

Thanks,

mips.h is only used on NetBSD and GNU/Linux, so, IMO, the right thing to
do here is just remove #define DATA_START in that file.

The solution should be the same in this file too.

OK to check in these 2 removals?

Indeed, thanks.  I've checked in the suggested fix.  Thanks.

FreeBSD and OpenBSD also use this, so I'm not sure this is right.  For
now, let's just use the __NetBSD__ conditional as originally suggested.
