 On MSYS I got this:

 This happened to me with an old version of the shell (say "sh --version").  I think perhaps the path-mangling is different.  With the MSYS recommended [wiki:Building/Preparation/Windows here], all is well.  The shell there is version 3.1.0(1).

-On Windows under MSYS, suppose your `_darcs/pref/defaultrepo` contains `simonpj@darcs.haskell.org:/home/darcs/ghc` (i.e. you are using an SSH connection). Then `darcs_all` will screw up: 
-{{{
-bash-3.1$ ./darcs-all pull
-== running darcs pull --repodir . simonpj@darcs.haskell.org:/home/darcs/ghc
-No remote changes to pull in!
-== running darcs pull --repodir utils/hsc2hs simonpj@darcs.haskell.org:/home/darcs/hsc2hs

-Looks ok, but look at the defaultrepo:
-{{{
-bash-3.1$ cat _darcs/prefs/defaultrepo
-simonpj@darcs.haskell.org;c:\msys\1.0\home\darcs\ghc/ghc
-}}}
-Glarp!  And indeed if you re-try the pull, bad things happen:
-{{{
-./darcs-all pull
-== running darcs pull --repodir . simonpj@darcs.haskell.org;c:\msys\1.0\home\darcs\ghc/ghc
-No remote changes to pull in!
-== running darcs pull --repodir utils/hsc2hs simonpj@darcs.haskell.org;c:\msys\1.0\home\darcs\ghc/hsc2hs

-Since defaultrepo is hosed, plain darcs fails too:
-{{{
-bash-3.1$ darcs pull
-Pulling from "simonpj@darcs.haskell.org;c:\\msys\\1.0\\home\\darcs\\ghc"...
-No remote changes to pull in!
-}}}
-This problem seems hard to fix, because it's a bug in MSYS's perl.  See #3499 for a workaround.

-This error is nothing to do with `darcs`!  The darcs-version test in `configure` uses `sort`, and it is picking up the Windows sort (in `c:\windows\system32`) instead of the MSYS or Cygwin sort.  
-
-Solution: either hack the configure script by hand, or (better) make sure that MSYS/Cygwin are in your PATH before Windows. Since `c:\windows\system32` is, by default, in the System Environment Variable called PATH, and System Variables come first when searching for paths, you'll have to put MSYS/Cygwin bin directory in the System PATH, before `c:\windows\system32`.

-(Incidentally, `find` is another program that Windows has too, with different functionality to Unix.)

-If this still doesn't work, try pulling 100 patches at a time using the {{{darcs pull}}} command (notice the lack of the {{{-a}}} flag).  Hold down 'y' until 100 or so patches are accepted, then hit 'd' to skip the rest; repeat until all patches are applied.  If this fails, try with less than 100 patches at a time (e.g., 50).

 === Ubuntu: {{{dash}}} vs {{{bash}}} ===
 In Ubuntu 6.10 the default system shell {{{/bin/sh}}} was changed to {{{dash}}} (The Debian Almquist Shell) instead of {{{bash}}}, see [http://wiki.ubuntu.com/DashAsBinSh DashAsBinSh]. This has been reported to break the GHC build. Until the GHC scripts are updated, the easiest way to fix this problem is to (as {{{root}}}) change the {{{/bin/sh}}} link back to {{{/bin/bash}}}. There should be minimal effect on the rest of the system, bar a small speed penalty for script heavy processes due to {{{bash}}} slowness.
