Proposal:
Add System.Info.isWindows :: Bool
This value should return True on all Windows systems (Win 1.0 ... Vista), and False on all other systems.
How about something slightly more general but still not quite so free form as the current System.Info.os :: String. Ian just added something to Cabal for it's own internal use to clean up the use of os-specific #cppery and use of System.Info.os which seems reasonable to me: data OS = Linux | Windows Windows | ... etc | Other String data Windows = MingW os :: OS So it's easy to pattern match on it and it gives us the ability to be more or less specific. For example in the windows case we could distinguish the environment, native vs mingw vs cygwin. That generalises isWindows and means we don't need isLinux, isOSX etc etc. Or if people really want those they can define them in terms of the above. So I suggest this (or something like it) as an alternative. While we're at it, discussing System.Info I think there are several more useful things we could add there, like exeExtension and probably several more. I seem to recall someone proposed a reasonable list on this mailing list some time ago, not just obj and dllExtension but a slightly wider rang of things. I can't seem to find it right now, does anyone else remember? Duncan
