Win32: configure without an intermediate makefile

Browse Source 
This batch file used `nmake` on the old `command.com` to extract the
parent directory name of this file and to get around the command line
argument length limit.  However, Windows 9X support as a build host
ended over a decade ago, and this file now utilizes the functionality
of `cmd.exe` already.
