[Haskell] New version of the HTTP module

[Graham Klyne]

I'm trying to check this out with some software that uses a previous 
version (HXml toolbox), and I get the following error from Hugs:
[[
Reading file "..\http\Browser.hs":
Type checking
ERROR "..\http\Browser.hs":865 - Type error in application
*** Expression     : ioAction $ openTCP hst
*** Term           : ioAction
*** Type           : IO a -> BrowserAction a
*** Does not match : (Int -> IO Connection) -> BrowserAction a
]]

It appears that the signature for "openTCP" has changed...

Previous version (HTTP.hs):
[[
openTCP :: String -> IO Connection
openTCP uri =
]]
-- http://homepages.paradise.net.nz/warrickg/haskell/http/HTTP.hs

Latest version (HTTP.hs):
[[
openTCP :: String -> Int -> IO Connection
openTCP uri port =
]]
-- http://www.dtek.chalmers.se/~d00bring/haskell-xml-rpc/HTTP.hs

But this is referenced by the copy of Browser indicated from your web page:
[[
                              ; c <- ioAction $ openTCP hst
]]
http://homepages.paradise.net.nz/warrickg/haskell/http/Browser.hs

I'm guessing that you also have a modified version of Browser.hs?
