And what comes out at
the end of the compilation is what the compiler 
creates. And the compiler is following the rules of the C standard and 
the rules of logic.
You claimed '"if (f != FALSE)" requires an explicit comparison with a 
second operand,' and that is factually wrong. No matter whether you are 
looking at it from the compiler perspective or from the perspective of 
an expressionist painter living in a yellow tree house on the bottom of 
Lake Tanganyika.

Don't even get

We better end this discussion, it's not leading anywhere. And you don't 
want me to turn into the Grinch and steal your Christmas.
