I did read it.

I think the programmer *must* worry about the details and must definitely
NOT use the booleans for anything C related. That was my point.

Attempting to cater for C code using BOOL or whatever type is misplaced.
C does not have a boolean type.

The standard says for "if" :

"In both forms, the first substatement is executed if the expression compares unequal to 0."

Treat it as such.
