Hi, 
 
I have just stepped over a patch suggested by Bernardo Innocenti in order to 
treat the case of "shift_count == 0" correctly. My presently suggested 
patch (above) only treats the case of negative shift counts.  
I did not realize that the case of "0" also is buggy. 
 
So for treating the shifting problem comprehensively, one should combine both. 
This could be done by replacing the checks for  "< 0" in my patch by checks 
for "<= 0". 
 
Yours, 
 
Björn
