Use the compiler-provided booleans if available, otherwise emulate

Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler.  Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.
