Subject: [PATCH 1/6] Werror: Fix casting wrong size integer to pointer
Date: Thu, 29 May 2008 19:17:26 +0100	[thread overview]
Message-ID: <20080529181726.5396.79336.stgit@warthog.procyon.org.uk> (raw)

Fix casting wrong size integer to pointer.  Smaller integers must be cast to
unsigned long then cast to a pointer.
