/* VC6-only fallback for the C99 <stdbool.h> header.
 *
 * Visual C++ 6.0 (_MSC_VER 1200) predates C99 and ships no <stdbool.h>;
 * in VC6's C mode `bool`/`true`/`false` are not keywords at all (they are
 * C++-only there). This project-local header is found ahead of any system
 * <stdbool.h> only because compat/msvc600 is placed first on the VC6 probe
 * scripts' include path (scripts/vc6-probe.sh, scripts/vc6-probe-core.sh);
 * it is never installed anywhere a standards-conforming compiler's own
 * <stdbool.h> would be found instead, so it never shadows a real one. The
 * _MSC_VER guard below is defence in depth for that same reason, and keeps
 * this file inert (and diagnosable, via the #error) if it is ever reached
 * by a compiler other than the VC6 this port targets.
 *
 * Modeled on the standard C99 <stdbool.h> contract: defines the macros
 * bool, true, false, and __bool_true_false_are_defined, and (matching
 * C99, which requires a program be able to #undef/redefine bool/true/
 * false) leaves them as plain macros rather than a typedef, so existing
 * C99-style `#undef bool` idioms, were CPython to use one, would still
 * work.
