Woohoo! Well done, karma++ - for being factually correct.
I agree--I wish System.Info.os worked differently, actually. But, there are apparently some people (not me) that use Haskell on Cygwin, and they need to be able to detect it, because e.g. Posix and Readline are available on Cygwin but not Mingw. Maybe os(x) should be either "mingw" or "cygwin"?
WRONG! Plain on old flat WRONG! If you run WinHugs on Windows having built WinHugs with Visual Studio, never even showing anything in the build process either mingw or cygwin, then mingw is the System.Info.os, which is, without a doubt, WRONG!
Perhaps this is the time for the Cabal people to push for a System.Info.windows flag, which is True on Windows and False if not? If you depend on an entirely wrong configuration variable, then that makes your configuration entirely wrong. For information, Yhc returns "Windows" if your OS is Windows - rather than returning the day of the week plus the birthday of your best friend (which makes similar sense to returning the installation status of an non-os component!).
I agree. I think they should be using some other method to find cygwin components. Eg they can check if the posix package is available or something. Duncan
