thanks for your answers - that looks very promising.

ah well, you do depend on a unixy build environment;-) I've got cygwin
myself, but I can't rely on my users having such things. More seriously,

a cursory browse of the sources shows up things like "POpen" and "Posix",
both no-nos, as far as portable ghc code is concerned (no longer supported
in the default ghc for windows, AFAIK). it would be good if ghc-users would
keep that in mind when writing portable Haskell code.

if you really need pipes to subprocesses, there's an apparently portable 
implementation in wxhaskell (Graphics.UI.WXCore.Process, no graphics 
needed - wxhaskell has lots of non-graphics widgets), or the up-and-coming 
System.Process. don't know about the rest of the Posix modules..

i don't have much time for testing right now, and "configure;make" stalls 
early on with a rather strange-looking message (see below), so I'll probably
have to leave that till next month. but, as i mentioned, i need something like
this, and if the idea is to provide a higher-level API on top of -package ghc, 
that sounds like a good way to go.. provided that the unix-"bugs" don't 
stop the show.
