See bug: http://hackage.haskell.org/trac/ghc/ticket/1590
Currently the recognised way to test if your application is being run
on Windows is:
.... = os == "mingw"
This is wrong on so many levels!
# The return result of os is NOT an operating system
# The result mingw does not imply that mingw is installed
# String comparisons are not very safe, a typo stops this working
# In GHC this comparison will take place at runtime, even though its a constant
Since nearly all uses of System.Info.os are to check if the operating
system is Windows, adding an explicit isWindows function would
Add System.Info.isWindows :: Bool
This value should return True on all Windows systems (Win 1.0 ...
Vista), and False on all other systems.
