Then those tools are broken per the C spec.

The C language spec, specifies _Bool as an integer type wide enough to at least store 0 and 1.
IOW, 0 and 1 are perfectly valid valus to assign to a _Bool.
And fundamentally that has to be so. That's how computers work. 0 is false, 1 is true.
The kernel is not the place to try and abstract such stuff, C is our portable assembler. We muck with hardware, we'd better know how the heck it works.
