Using this helper:

#include <stdio.h>
main() {
    printf("sizeof(_Bool)=%i bytes\n", sizeof(_Bool));

I get:

sizeof(_Bool)=4 bytes

on a G4 PPC.

Seems strange to me, but reasonable since it is defined like this
in stdbool.h:

#if __STDC_VERSION__ < 199901L && __GNUC__ < 3
typedef int     _Bool;
