The following commit has been merged in the experimental branch:
commit 2023cfea0fa56aa15396d6c0a43b290aa6e6c9b4
Author: Måns Rullgård <mans at mansr.com>
Date:   Thu Mar 11 02:32:01 2010 +0000

    Add some required casts
    
    These casts are correct and safe.  The pointers are guaranteed to
    have proper alignment, and aliasing is not a problem with character
    types.
