Not really. As Max said, the environment in which the postinstall scripts run is the same as the one you'd get when you run them on the command line (albeit from a non-login /bin/sh). That environment will contain all of the Windows-set environment variables. If the tools require that some variables be unset (because they might throw the tools off, for example), the variables have to be unset in the postinstall script -- setup.exe can't be expected to know all of the variables potentially conflicting with all of the packages. OTOH, I've already submitted the patch to setup.exe that kills stdin in postinstall scripts, so that even if some tool asks for input, it'll just get EOF.
