[I have studied, meanwhile]

Actually the point of Rabin is, I think, that the patch is not needed.
Our "bool" is the C99 "_Bool" type, for which the compiler
automatically converts all non-0 assignments to 1.  Even if storage
is still one byte.

IIUC, the point of _Bool is allowing comparisong with "true", while in
general non-0 is considered true if evaluated in a conditional
but may be "!= 1" so "!= true" if compared explicitly.

You can compile a one-liner to check. I used a few more:

    _Bool i[10];

    int main(void)
    {
        i[0] = 1;
        i[1] = 10;
        return i[0];
    }
