Much as we all hate cpp, I'm afraid the standard libraries are already heavily littered with #ifdefs. Getting rid of them is basically impossible. I guess it's the community's choice of what is important, but in my experience this is a major impediment to distributing portable programs written in Haskell for use by non-Haskellite end users.
Malcolm only pointed out that it is basically impossible to *implement* the libraries without #ifdefs due to the different capabilities and internal design choices of the Haskell systems. *Using* these libraries should of course be possible without reverting to CPP.
There should be no externally visible type differences in standard libraries. [...] So I would hope, but I seem to recall coming across some variations of function parameters between systems. I don't remember where.
That shouldn't be the case. I guess we still have some dark corners in the POSIX vs. non-POSIX area, suggestions for improving this (and other places, too, of course) are highly welcome. It would really be helpful to know what caused your grief... Cheers, S.
