Bill Currie d1fcfd1939 Implement --traditional so qfcc can be a nicer qcc. This disables several 
keywords (quaternion integer function for break continue switch case default
NIL struct enum typedef) and converts some errors to warnings (assignment to
constants, insufficient function arguments, return; from non-void function,
anal function `pointer' type checks)
