updated <io.h> for open() use G_PI instead of M_PI

2005-07-03  Hans Breuer  <hans@breuer.org>

	* **/makefile.msc[.in] : updated
	* gtk/gtkiconcache.c : <io.h> for open()
	* gtk/gtkstyle.c : use G_PI instead of M_PI

	* gdk/win32/gdkcursor-win32.c : implement gdk_cursor_new_from_name()
	by mapping the lower case win32 api name to the respective cursor.
	E.g. pass "wait" to get the IDC_WAIT cursor. Also allows to load
	cursors from named resources in the executable.
	(gdk_cursor_get_image) : just return NULL for now.

	* gdk/win32/gdkgeometry-win32.c : implement gdk_window_move_region()
	by delegation to ScollWindowEx(), untested.

	* gdk/win32/gdkwindow-win32.c : stub for gdk_window_set_urgency_hint()
