install doesn't install under Windows

[Neil Mitchell]

Hi

Under Windows, for an application, with the example of Alex:

runhaskell Setup configure
runhaskell Setup build
runhaskell Setup install

This however doesn't result in an Alex binary that can be found by
Cabal, i.e. to build Haddock.

So there are a few options:

1) Move alex.exe into some global Haskell directory for binaries
(which is on the PATH)
2) Make an alex.bat in some global Haskell binary directory (on the PATH)
3) Make Cabal detect wherever it puts alex, so it can then use it.
4) Put whereever it puts alex on the PATH.

All have plus and minus points, I'd lean to 1 (since thats what I
already do when installing things).

Thanks

Neil
