[PATCH] FreeBSD/Alpha support

[Mark Kettenis <kettenis@wins.uva.nl>]

I checked in support for FreeBSD/Alpha.  This is tested on FreeBSD
5.0-CURRENT, but it should work on FreeBSD 4.x just as well.

I'll put some blurp in the NEWS file (which reminds me that I still
have to do this for FreeBSD/i386 too).

Mark


2000-05-31  Mark Kettenis  <kettenis@gnu.org>

	Add support for FreeBSD/Alpha.
	* alphabsd-nat.c, config/alpha/fbsd.mh, config/alpha/fbsd.mt,
	config/alpha/nm-fbsd.h, config/alpha/tm-fbsd.h,
	config/alpha/xm-fbsd.h: New files.

You should look at the bright side of things - how many times more your
name pops up in the ChangeLogs :-)

I've just committed the patch below.

	* gnu-regex.c (re_match_2_internal): Revert 2000-05-27
	patch which removed use of PARAMS from declaration.  This
	file should not have been touched as it is supposed to track
	the version in glibc.
