[Pharo-project] Zeroconf and Windows: recommended environment?

I am using MobaXterm (http://mobaxterm.mobatek.net/) on Windows to have a Unix-like environment. Thing is that the shell there is bash but all utilities (like unzip etc) are based on busybox (http://www.busybox.net/). This means that not all options are available. Also, the $OS variable looks like to give Windows_NT, which then leads to the "Unsupported OS" message (for the VM for example). What is the environment you guys do use for testing those scripts on Windows (Windows 7 in my case)? Thanks in advance, Phil
