Subject: [PATCH REPOST] [3/3] Replace macro recursion with more conventional loop
Date: Tue,  4 Mar 2008 22:13:32 +0100 (CET)	[thread overview]
Message-ID: <20080304211332.2F4C61B4199@basil.firstfloor.org> (raw)
In-Reply-To: <200803041013.139953228@firstfloor.org>


The early exception handlers are currently set up using a macro
recursion. Replace that with a standard loop.

Noop patch, just a cleanup.
