From 7876e4488ffee77940ead9f4e88e5293d63f8dcc Mon Sep 17 00:00:00 2001
From: Richard Levitte <levitte@openssl.org>
Date: Thu, 27 Sep 2001 15:43:55 +0000
Subject: [PATCH] Stop thinking arguments starting with - are algorithm
 identifiers. Show timing parameters and timing functions used. It looks like
 some Linuxen have very weird settings for CLK_TCK.  I'm very unsure about
 this change and will investigate further.
