Re: Network problem with ghc on WinXP

      Me neither; I'm guessing it goes back to the days when
PortNumber used to be a type synonym (and synonyms
could/had to be exported with (..).)

Is there a reason not to export PortNumber abstractly?  I can't think of
one off-hand.
Cheers,

Hi there,
looks like a network byte-order vs host byte-order gotcha.
Never use the PortNum constructor, but declare 'portnum'
to have type PortNumber and simply drop the use of PortNum
in your code alltogether. Alternatively, use intToPortNumber
to translate between Int and PortNumber.
