So this might be a bug in C::Scan (which I have installed via cpanm
from HVDS/C-Scan-0.74)?

booltest.h:
#include <stdbool.h>
void h2xs(bool b);
With a trivial implementation in booltest.c:
#include "booltest.h"
void h2xs(bool b) {
(void)b;
}
However, the same thing works fine with _Bool instead of bool+stdbool.h.
