Issue #9566: compile.c uses Py_ssize_t instead of int to store sizes to fix compiler warnings on Windows 64-bit. Use Py_SAFE_DOWNCAST() where the final downcast is needed. The bytecode doesn't support integer parameters larger than 32-bit yet.

#include "Python.h"

#ifndef PLATFORM
#define PLATFORM "unknown"

Py_GetPlatform(void)

	return PLATFORM;
