GHC 6.0 on Win32: warning!

Dear GHC users

If you use GHC 6.0 on Win32, read on. Otherwise, don't bother.

Some of you have already discovered that GHC 6.0 has a nasty bug: if you
	ghci foo\Baz.hs
and there is any error at all in Baz.hs, then GHC deletes the source
file!   This seems like excessive punishment for a type error.

So far as I am aware, this only happens
	* on windows
	* with ghci (not ghc)
	* if you put back-slashes in the path
There's no problem if you use forward slashes, or no slashes at all.

This will be fixed in 6.0.1, which we'll put out in a couple of weeks,
but meanwhile you might want to be aware of it.  A bit of an egg-on-face
job really.
