The reason it does not work, is that you first try to define +32768 and then negate the result. Since +32768 can only be expressed as a long, you end up with a long variable. Using fix is a solution, but you could also use the bitwise not operator, if you feel adventurous:
IDL> a = not 32767
IDL> help, a
A INT = -32768
