gtk/gdk/win32/gdkwindow.c
Tor Lillqvist cf451eb447 Fix from Simon Kelley: Set expose_count in GdkEventExposes correctly.
* gdk/win32/gdkevents.c (gdk_event_translate): Fix from Simon
Kelley: Set expose_count in GdkEventExposes correctly.

* gdk/win32/gdkwindow.c: Remove dead code (#ifdef
MULTIPLE_WINDOW_CLASSES).

* gdk/win32/gdkdraw.c (gdk_draw_line): Workaround from Hans Breuer
for bug in NT, apparently NT *does* draw the end pixel, too, in
LineTo with a one-pixel pen, so we don't have to do it ourselves.
