[Haskell] readline troubles

[Arjan van IJzendoorn]

Hello all,

Using GHCi 6.2.2 and HaXml-1.12 gives you the output below on Windows 
with Cygwin. I've seen this message on several other occasions and I 
finally managed to fix this using info at:

http://www.haskell.org/pipermail/glasgow-haskell-users/2004-November/007370.html
   (thank you, Sigbjorn!)

However, this is no trivial job and everyone who wants to compile a 
project using readline on Windows needs to patch this.

My question is: has this been solved in GHC 6.4 and if not, can this 
easily be solved? Maybe by including some version of readline in the 
Windows GHC installation?

Cheers, Arjan van IJzendoorn
