Fixes windows builds on latest Haskell Platform. Should be hopefully applied to
2.4 branch as well. (To successfully build, you will also need hashed-storage
0.4.13, to be released.)

Yours,

I talked briefly with Petr on IRC about this.

Aside from accounting for the GHC 6.12 internal representation for file
paths, this replaces our System.Posix.Files compatibility code (for
Windows) with a 3rd party package unix-compat (by Bjorn Bringert).

We agreed that whatever the risks of this action are, the alternative
(doing it ourselves) is worse.  So press on...

No comments, just reading below.

We nuke these and re-export them from System.PosixCompat.Files.

These are motivated by the recent GHC 6.12 changes pointed out by Brian
Smith on Reddit and discussed with Simon Marlow.
