From 836fc7778513fa97c1852444155f82627ecbb8cd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Reimar=20D=C3=B6ffinger?= Date: Thu, 28 Jan 2010 21:01:50 +0000 Subject: [PATCH] Move variable declaration to block where it is used and simplify code. Avoids a (incorrect) "possibly used uninitialized" warning, no measurable speed difference.
