Synopsis: Inconsisitency using right shift operator (signed vs. unsigned shift)
State-Changed-From-To: open->feedback
State-Changed-By: neil
State-Changed-When: Wed May 8 10:38:30 2002
State-Changed-Why:
Can you reproduce this behaviour for a shift of less than 32 bits?
A shift of the same number of bits as the width of the
type gives undefined behaviour, so the testcase you post
is not a bug as-is.
