Yeah I'd welcome input from any windows programmers out there, especially
if you've tied standard windows32 menus into an SDL application.  The code
seems incredibly straightforward - not much room for misunderstanding -
and yet this problem persists.

All the windows-specific code is in src/windows32/.  The menus are
created in the init() function in src/windows32/ui_windows32.c and
attached to the main windows in sdl_windows32_update_menu() in the
same file.  Event handling for windows-specific events is delegated to
sdl_windows32_handle_syswmevent(), also in the same file.

The windows themselves are created in the cross-platform SDL "modules",
but by the time it comes to attaching the menu, it's just a normal HWND
that SDL is able to retreive.
