patching a lower version.

I'm trying to use the file upload patch......on 4.0.4pl1.... but it only says its for 4.0.6.....so will it not work on 4.0.4pl1? and if so......how does it work? I got this when running it...... Hmm... Looks like a unified diff to me... The text leading up to this was: -------------------------- |--- rfc1867.c.1.62.2.1 Tue Jun 19 18:54:44 2001 |+++ rfc1867.c Tue Feb 26 15:52:55 2002 -------------------------- Patching file rfc1867.c using Plan A...
