Restating problem this way leads to this idea:

struct PythonStaticState {
    ...
};

#ifdef EMBED
#define GLOBAL_STATE_MACRO PythoStaticState globalPythonState,
#else
#define GLOBAL_STATE_MACRO
PythonStaticState globalPythonState;
#endif

PyObject * PyAnyApi(GLOBAL_STATE_MACRO, a, b, c, d)
{
	globalPythonState.var1 = 0;
}

and using good compiler and linker for nonembeded case ;^)
