From 7fb1be73734915e027f86aca9ba62b86c56ca787 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Mon, 24 May 2004 17:41:47 +0000 Subject: r853: remove a real big bunch of unused code I really think that this is needed to get a better overview of what is currently used Also this stuff is really out of date so if we really ever need some of this stuff back, a 'svn copy' from the SAMBA_3_0 branch should be no big problem... metze (This used to be commit 972598d511c64f29bdc849fe58c9c82fbcf6a4a2) --- source4/include/includes.h | 4 - source4/lib/basic.mk | 2 - source4/lib/username.c | 83
