From 3c06f6a0b234822c7b2d6c63ef1aaf554af7167b Mon Sep 17 00:00:00 2001
From: Ben Lindstrom <mouring@eviladmin.org>
Date: Wed, 31 Jan 2001 21:52:01 +0000
Subject:  - (bal) Reorder.  Move all bsd-*, fake-*, next-*, and cygwin* stuff
 to    openbsd-compat/.  And resolve all ./configure and Makefile.in issues   
 assocated.

Logic:

* All OpenBSD functions should have the same filename as in the OpenBSD
  tree

* All 'home brew' functions have bsd-* infront of them.

* All 'not really implemented' functions have fake-* infront of them.
