int is always the fastest to process because it's defined to be the same
size as the registers on the CPU. bool is a C++-ism that got pulled into
C with C99. A C-program gains nothing, but loses portability by using bool
instead of int. Only if you compile a program with -Os (optimize for size,
not speed), will you stand a chance at losing performance by using bool
instead of int, as you can get several bool's contained in one int.
