[mingw only]
Provide (unsatisfying) workaround for pesky Ctrl-C issue, whereby a
cygwin-based bash will terminate the 'ghci.exe' wrapper without the
wrapper process getting a chance to respond (and shut down its child,
if nothing else.) The result instead being that the child (ghc.exe) ends up
lingering in the background.
To steer users away from such badness, the wrapper checks to see whether
it is running in a *nix-like shell, and if it is, issue a warning that
it would be better to invoke GHCi using the 'ghcii.sh' shell script instead.
Merge to STABLE.
