Just checked and _Bool is also 1 byte, same as C++. What i don't understand yet is to which standard does the current _bool conform? I couldn't find any platform with int sized bool.

Yes, `_bool` is a problem. I'll add a `_stdbool` that corresponds to
`bool` from C99's <stdbool.h>, which I imagine must be the same as
`bool` in C++.

i guess this shouldn't happen:

$ cat s.cc
#include <stdio.h>
int main()
     printf("%zu\n", sizeof(bool));
$ g++ s.cc -o s
$ ./s
