Description Coriiander 2019-03-22 15:46:45 UTC 
FILE: SDL2-2.0.9\src\events\SDL_mouse.c
FUNCTION: SDL_MouseDoubleClickTimeChanged

For Win32-platforms this function makes a call to GetDoubleClickTime, as below:

#ifdef __WIN32__
mouse->double_click_time = GetDoubleClickTime();
#else

While building a warning is issued about the GetDoubleClickTime symbol not being defined - which may lead to undefined behaviour, including crashes.

To use GetDoubleClickTime include <windows.h> and link to user32.lib.
You can do so at the top of the file:

#ifdef __WIN32__
#include <windows.h> /* Needed for GetDoubleClickTime. Cheers Coriiander! */
#endif
