+	* fhandler_raw.cc (fhandler_dev_raw::open): Eliminate compatibility
+	code since no Win32 device names are used anymore.
+	* fhandler_tape.cc (fhandler_dev_tape::tape_set_blocksize): Allow
+	0 as blocksize to indicate variable blocksize.
+	* path.cc (win32_device_name): Generate NT internal device names
+	using upper/lower case names for readability.
+	Generate \DosDevices\<letter>: device name for mount table
+	compatibility devices.
