State-Changed-Why:
    Not a bug. An immediate value must be a compile time constant. A
    procedure parameter is definitly NOT a compile time constant. gcc
    can deduce its value for an inline function if certain optimizations
    are done. You can request these optimizations with the various -O
    flags and in this case the code compiles. Note that there is no
    guarantee that this will remain true in the future.
    
    Also note that the `I' constraint has this description on the avr
    architecture:
    
    |    `I'
    |          Constant greater than -1, less than 64
