bool, false and true are keywords in C++ and don't require #inclusion
of any header. The mentioned compiler is not conforming to ISO/ANSI C++
(perhaps because it's old).

In C99 _Bool is a keyword, and bool, false and true are macros defined
in <stdbool.h>.

True converted to an integer is 1, not -1.
