  Wrong.

>"if either operand is long ... that is the type of the result"
  Correct.

>Therefor you are assigning a long to an int.
   Wrong. He is assigning adding an int to a long and then assigning
   the LONG result to a LONG.

   Therefore, the originator of this note is correct, his compiler has
   a blatant bug.

   Please read a note carefully before giving out incorrect and/or
   misleading advice.
