Well, I'd say an error makes some sense.  Except, this is an explicit cast so one assumes 
the user has some clue -- and if not, they soon will.  So... I would say the int version 
is used, and that possibly a warning about possible data loss is generated when -w is 
given.  Its the same concerns as:

# int foo = 0xf0f0f0f0;
# short bar = cast(short)foo;

Casting always has its dangers.
