/* In static compilation, DllMain doesn't exist and so DLL_THREAD_DETACH
* case is never called and thread destroy notifications are not triggered.
* To ensure that notifications are correctly triggered in static
* compilation mode, we call directly the "detach" function here right
* before terminating the thread.
* As all win32 threads initialized through the glib API are run through
* the same proxy function g_thread_win32_proxy() which calls systematically
* g_system_thread_exit() when finishing, we obtain the same behavior as
* with dynamic compilation.
*
* WARNING: unfortunately this mechanism cannot work with threads created
* directly from the Windows API using CreateThread() or _beginthread/ex().
* It only works with threads created by using the glib API with
* g_system_thread_new(). If users need absolutely to use a thread NOT
* created with glib API under Windows and in static compilation mode, they
* should not use glib functions within their thread or they may encounter
* memory leaks when the thread finishes.
