with the large number of "just chatting" messages on
haskell-cafe, it is all too easy to miss problem reports
here. you might have a better chance asking on more
specific lists, eg. for ghc use, or library issues

the standard build of ghc uses cygwin tools to build a
no-cygwin ghc. in particular, ghc is not linked with the
posix-emulation libraries of cygwin, nor does it use cygwin's
compiler or linker. so, unless you've made a non-standard
cygwin-linked ghc, the unix package is unlikely to build
with that ghc.
do you really need the unix package? a lot of general
functionality is available in platform-independent haskell
libraries, and some of the unix-package functionality is
available in unix compatibility packages.

it is quite possible to work with a no-cygwin ghc in
a cygwin environment. the environment supplies the
build tools that some haskell packages and tools
need for configuration and build, then the no-cygwin
ghc produces a no-cygwin executable (which can
be run from cygwin, or as any other windows-only
that is indeed the default setup for ghc development
on windows, so darcs, haddock, etc. should work in
it, apart from a few rough edges. helping to smooth
those edges, where things that should work don't
quite work on windows, would be a significant
ideally, all haskell tools should work on windows
entirely without non-windows tools, and while that
is not likely in the near future, many of them already
do, and reducing unix-dependencies helps to make
haskell easier to use for windows users (just as
avoiding windows-dependencies ensures that unix
users are not excluded!-).
