1d35f4dd9e make ~ work for v6 progs by implementing ~x as -1 - x (will give bogus

5d7135600e gah, that /did/ work, dunno what happend. must have done a tweak before
committing again :/ This currently produces some pseudo warnings about
dangling temps, but that's better than producing broken code

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

anal function `pointer' type checks)

	extract_type uses get_type to return the qc type enum.
