From 8b5ec0875c8d00d62034ed1df7188b7c75baba3a Mon Sep 17 00:00:00 2001 From: Reimar Döffinger Date: Fri, 17 Apr 2009 08:42:08 +0000 Subject: Change tgq_decode_mb function arguments from using int8_t to uint8_t, this does not really change the code (x86_64/gcc-4.3.3 results stay unchanged) but avoids several casts and an aliasing violation that broke decoding at least on PPC64/gcc-4.1.2.
