I get many of these errors building kaffe-x11:

   317.     dd = dd << 9 | dd >>> -9;
									 ^^
									 *** Semantic Caution: The shift count -9 is negative; it will be masked to the appropriate width and behave as a positive shift count.



   130.                                 long time = ((other[0] & 0xFF) << 40) +
                                                                          ^^
*** Semantic Caution: The shift count of 40 is >= the 32-bit width of the type.


   131.                                             ((other[1] & 0xFF) << 32) +

And similar errors with kaffe-esound:

Any clues on where I went wrong are appreicated?
