ACK! Please refer to page 49 of K&R or any other C book which has a
precedence table. "a = b == c" must be parsed as "a = (b == c)" by
laws of precedence which have been in C for a very long time.
A C programmer who does not know his precedence laws by heart had better
use a lot of parentheses or he can expect a LOT of problems.

These are my own opinions and FPS doesn't even know about them.
