Oh, I realized that PyGILState_STATE may also be included only if Python
is compiled with threads.

PyGILState_Ensure() and PyGILState_Release() could be no-op yes, it
would simplify the usage of these functions. For example:
#ifdef WITH_THREAD
PyGILState_STATE gil;
#endif
fprintf(stderr, "object : ");
#ifdef WITH_THREAD
gil = PyGILState_Ensure();
#endif
(void)PyObject_Print(op, stderr, 0);
#ifdef WITH_THREAD
PyGILState_Release(gil);
#endif

Even without threads, a Python process has a PyThreadState structure, so
PyGILState_GetThisThreadState() can be patched to work even if Python is
compiled without threads.

Would you like to work on such patch? Or at least open an issue?
