I recently committed a W32 g_poll() test to glib git master. You can find it
here[1].
If you look closely, you'll realize that g_poll() does almost nothing - it's
just a glorified WaitForMultipleObjectsEx(). All the magic happens in GSource
implementation, and that's what you must use, unless you're willing to do what
i did in that test and do all the pre- and post-processing yourself. Note that
i omitted a lot of corner cases in the test though.
