It would be nice to get ride of #include <windows.h> in Python headers. The
<windows.h> was introduced by this commit:

bpo-30860: Consolidate stateful runtime globals. (#3397)
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState
struct
* add a check-c-globals.py script that helps identify runtime globals
Other globals are excluded (see globals.txt and check-c-globals.py).
The current problem is that we need the HANDLE type which comes from
<windows.h> to get the full structure:
typedef struct _PyCOND_T
{
HANDLE sem;
int waiting; /* to allow PyCOND_SIGNAL to be a no-op */
} PyCOND_T;
I tried to avoid "HANDLE" using:
typedef struct _PyCOND_T
{
void* sem;
int waiting; /* to allow PyCOND_SIGNAL to be a no-op */
} PyCOND_T;
... but then pycore_condvar.h compilation fails on "typedef CRITICAL_SECTION
PyMUTEX_T;": CRITICAL_SECTION type is not defined :-(
By the way, Python still uses _PY_EMULATED_WIN_CV by default, whereas we want
to drop Vista support: bpo-32592.
