e17604f9c2 remove all arbitrary limits except for globals. they'll need a little more
work. Once they're done, it should take quite a big mod to crash qfcc due
to too many strings/statements/etc :)

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)
