I have noticed that after some updates to the compiling tools my scripts are broken.
Please start the shell with "win32con.bat" instead of "conemu.bat". Now you can start the compiling-script direct with the "compile-xxxx.cmd". I will change my guide to this procedure as it makes more sense to start a cmd.exe that executes the cmd-script. With the bash-shell I have started also a cmd.exe within first. .........thats tooooooooooo complicate, agreed :-)
