/* Focused, isolated compile smoke test for compat/msvc600/stdbool.h under

 * Deliberately does NOT go through pycore_interp.h or any other pycore_*.h
 * header: this isolates the result to the <stdbool.h> shim itself, the
 * same way scripts/fixtures/vc6_atomic_smoke.c isolates pycore_atomic.h.
 * Modules/main.c (see scripts/vc6-probe-core.test.sh) is the real-header
 * reference case that proves compat/msvc600/stdbool.h is actually what
 * pycore_interp.h's `#include <stdbool.h>` resolves to via the VC6 probe
 * scripts' include path.
