Well, it's certainly a valid option, and C++ compilers seem to
generate
the same "CMP boolRm, 0" in both cases (though the latter could
actually
generate the potentially faster and better "OR boolRm, boolRm"
instead).
"if (f != FALSE)" and "if (f)" are exactly 100% the same for the
compiler. "if (f)" is nothing but a synonym for "if (f != 0)" and
FALSE is 0. Whether it creates a CMP, or an OR or a TEST is all up
to the compiler and it will be the same in both cases. If it was not
the same, there is something ... well not neccessarily "wrong" but
at least very strange with the compiler.
