Hi,

I'm against "signed shift right", because the reason for the macro is exaclty that CPUs do a "signed" shift right. John does a "signum(arg) * right_shift(abs(arg), number_of_positions)". So maybe it's the signed_unsigned_shift_right(), susr() to be cryptic ;-)

I see, so that would be a divide by 2^shift?

Well, nevermind - I guess the patch is better than what was
there before.
