JFYI, there is not really a "native batch script that all Windows comes with", there is a command interpreter that can be command.com (windows 9x/Me) or cmd.exe (NT 4.00 and above), each OS may have (or may have not) different behaviours/different syntax for the scripts, and - to be picky - the .bat extension is the "historical" one associated to command.com, cmd.exe is associated with both .bat and with the (suggested) .cmd extensions.
Your compiler[1] clearly needs cmd.exe.
[1] maybe translator would be more appropriate, as nothing is compiled
