Just a remind: at least we would be in good company, as ANSI C does not
offer this operation too :)

  ISO/IEC 9899:1999 (E)
  6.5.7
  The result of E1 >> E2 is E1 right-shifted E2 bit positions.  If E1
  has an unsigned type or if E1 has a signed type and a nonnegative
  value, the value of the result is the integral part of the quotient of
  E1 / 2E2.  If E1 has a signed type and a negative value, the resulting
  value is implementation-defined.
