commit 369b64b4279008f732807c7015501cad75610f0e
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Jan 4 21:57:21 2011 -0500

    Brush up configure output
    
    Show used X extensions, print backends, etc.
    Also make configure abort in some more cases when explicitly
    enabled options are missing dependencies.
