Cygwin version
I want a _real_ cygwin version of darcs. The non-deterministic pseudo-cygwin *nix/Windows hybrid currently available has just too many problems integrating into cygwin, that I want to use as my TeXing and minor coding environment. A real cygwin version of darcs would seem to depend on a real cygwin version of GHC. Is there any easy way to compile one? Otherwise I may have to abandon darcs (and Haskell software in general) for Mercurial. (Thanks to the over-bearing cabal and resulting hsc2hs etc. build problems with conventional Makefiles, I have already pretty much already abandoned my own Haskell projects.) -- Stop Gnomes and other pests!

I presume that the mingw-ghc used the include mingw gcc, not cygwin's gcc.

My preferred spec would be roughly
{-# NOINLINE f #-}

be taken as go-ahead for analysis-based recursion unfolding)
{-# INLINE f PEEL n #-}
inline calls *into* recursive f (called loop peeling for loops)
{-# INLINE f UNROLL m #-}
inline recursive calls to f *inside* f (called loop unrolling for
loops)
{-# INLINE f PEEL n UNROLL m #-}
combine the previous two
The problem here is that this only works for directly recursive
functions which I, for instance, don't normally use in high-
performance code. Most of my loops are pipelines of collective
combinators like map, filter, fold etc. because these are the ones
that can be fused automatically. Unless I'm misunderstanding
something, this approach doesn't handle such cases.
