+	Throughout, use user32 UNICODE functions rather than ANSI functions.
+	* autoload.cc: Convert all definitions for ANSI user32 functions to
+	definitions for the corresponding UNICODE function.
+	(SendMessageA): Remove.
+	(SendNotifyMessageW): Define.
+	* fhandler.h (fhandler_windows::is_slow): Remove.
+	* fhandler_windows.cc (fhandler_windows::write): Use SendNotifyMessageW
+	call rather than SendMessage to make function always return immediately.
+	(fhandler_windows::read): Make function interruptible and a cancellation
+	point.  Handle O_NONBLOCK.
+	* select.cc (peek_serial): Don't wait for signal_arrived here.
+	* window.cc (wininfo::winthread): Call CreateWindowExW directly rather
+	than CreateWindow wrapper.
