This is no longer the case with c99.  According to section 6.5.2.4
(Postfix increment and decrement operators), "The result of the postfix
++ operator is the value of the operand.  After the result is obtained,
the value of the operand is incremented".  So, your interpretation may
have been correct at one point, but it is certainly not correct at
THIS point.
