commit 811a643d3eadb4baf4d21f5fef7b4f0c17318167
Author: Peter Hutterer <peter.hutterer at who-t.net>
Date:   Fri Apr 8 13:27:47 2011 +1000

    Put a #warning and #error in to avoid unsuspecting XI 2.1 users.
    
    The #warning directive is intentionally outside the define to disable the
    error. Early adopters of the protocol can't see this warning often enough.

commit e03bd010b8053ee23e9e6a0bad249107d2b1b6c0
Author: Peter Hutterer <peter.hutterer at who-t.net>
Date:   Fri Apr 8 13:26:27 2011 +1000

    Add define for 2.1 support
    
    Technically, this define is rather pointless as long as we refer to XI 2.1
    as 2.1. But it comes essentially for free, so why not.
