I wanted to include 'installHandler sigPIPE Ignore Nothing' (as mentioned in the documentation of the Network module) in my program to make it more portable. Perhaps 'installHandler' could be set to a constant 'return ()' on windows?

The System.Posix.Signals interface doesn't make any sense on Windows. We could duplicate the whole interface with "do nothing" functionality, but it's not clear that this is the right thing to do (the interface is quite a bit more than just installHandler). You want something like this: #if __GLASGOW_HASKELL__ < 603 #include "config.h" #else #include "ghcconfig.h" #endif #ifdef mingw32_TARGET_OS ignorePipeSignal = return () #else import System.Posix ignorePipeSignal = installHandler sigPIPE Ignore Nothing #endif Maybe it would make sense to include this in a library somewhere.
