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.
The problem here is that, when using Hugs, the source code of the libraries needs to be part of the input to Hugs.
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...
If I rediscover it, I'll send a note to this list. #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
