gtk/gdk/win32/gdkevents-win32.c
Hans Breuer 6ff97d2e0b disable USE_MMX for msvc build cause the assembler doesn't fit and is out 
2001-03-31  Hans Breuer  <hans@breuer.org>

	* config.h.win32.in : disable USE_MMX for msvc build cause
	the assembler doesn't fit and is out of my scope. Disable
	USE_GMODULE for msvc build as wel. The right way to share
	binaries on win32 would be to use libtiff.dll etc. To reduce
	installation hassles IMO it's better to include all fileformats
	builtin to gdk-pixbuf

	* gdk-pixbuf/makefile.msc : new file

	* gdk/gdk.def : updated

	* gdk/win32/gdkevents-win32.c : don't erase the background if
	.no_bg is set. It improves the scrolling (e.g. of testgtk main
	buttons
	* gdk/win32/gdkgeometry-win32.c : added comment about the above

	* gdk/win32/gdkwindow-win32.c : added three new functions like
	the X version. Only one is implemented, because the other two
	"gdk_window_begin_(resize|move)_drag" got no docs and appear to
	be default behaviour on win32 anyway ...

	* gtk/gtk.def : updated

	* gtk/makefile.msc.in : update for new files, use glib-genmarshal
	from where it was built and add an additional rule to automagically
	build gtkmarshal.[hc]

	* gtk/gtkfilesel.c (open_new_dir) : don't increase n_entries
	before array access for the current entry isn't finished

	* gtk/gtktreeitem.c (gtk_tree_item_subtree_button_click) :
	use g_return_val_if_fail

	* gtk/testgtk.c (window_controls) : don't use the *wrong* size
	for the static array, but let the compiler calculate it. It
	makes me wonder if gcc isn't capable to catch bugs like this ...
