/* Focused, isolated compile smoke test for Include/internal/pycore_atomic.h
 * under VC6/_M_IX86.
 *
 * Deliberately does NOT go through Python.h or any other pycore_*.h header:
 * pycore_interp.h (reached transitively from a real core translation unit
 * like Modules/main.c) additionally requires <stdbool.h>, a separate,
 * unrelated VC6 gap tracked in PORT_STATUS.md. Isolating pycore_atomic.h
 * here keeps this probe's result attributable to the atomics compatibility
 * work specifically.
 *
 * Py_BUILD_CORE is supplied by the probe script (/D Py_BUILD_CORE), the
 * same way it is for a real core translation unit. <inttypes.h> (resolved
 * to compat/msvc600/inttypes.h for VC6 via the include path) provides
 * uintptr_t, which pycore_atomic.h needs but does not itself include; in
 * a real build this comes from Python.h/pyport.h, included ahead of any
 * pycore_*.h header.
