Your condensed summary was my understanding, but if I try to issue
Cabal install --reinstall cmu
It works every time from a MSYS shell, but with Cygwin I get
If MSYS works for you, why not stick with it?-) Cygwin with MinGW tools should work, but it is very easy to mess up with this setup (configure scripts might not notice that they are on windows and use the wrong calling convention, Cygwin libraries and compiler tools might be called accidentally if they are installed, and so on). Of course, the more people give up and switch to MSYS, the smaller the chances that such bugs (things that accidentally work when using MSYS, or with a certain directory layout) get reported and fixed.
Linking dist\build\cmu\cmu.exe ... C:\Program Files\Haskell Platform\2010.1.0.0\lib\..\mingw\bin\windres: can't open temporary file `\/cca04932.irc': No such file or directory cabal.exe: Error: some packages failed to install: cmu-1.2 failed during the building phase. The exception was: ExitFailure 1
('cmu' is just an example; the same behaviour seems apparent whatever the package; I see something very similar when I ask GHC to compile hello.hs.)
You could try running 'ghc -v hello.hs' and check the windres command for oddities. I have no problems building a simple hello world from Cygwin: $ uname -a CYGWIN_NT-6.1-WOW64 VAIO 1.7.5(0.225/5/3) 2010-04-12 19:07 i686 Cygwin $ type ghc ghc is hashed (/cygdrive/c/haskell/ghc/ghc-6.12.2.20100522/bin/ghc) $ ghc tst.hs $ ./main.exe Hello, World!
The general answer I seem to have been getting (and responses I have seen elsewhere top this problem) is 'don't expect the Haskell tools to work with Cygwin'.
That tends to be a self-fulfilling prophesy, similar to 'don't expect the Haskell tools to work on Windows (because so many people rely on unixisms)'. But the result is that problems do surface more often in this configuration. If you want to investigate, you could file a report on the HP trac. Claus
At any rate it seems that, for some people at least, the latest version of the Haskell tools won't work when launched from Cygwin Bash.

Thanks Stephen--that was related to my original question, about using HP with Cygwin. The answer seems to be No!--you must use MSYS (for real work).
The short version:
- Cygwin provides commandline tools, compilers and libraries - MSYS provides commandline tools for the MinGW compilers and libraries
You can use the commandline tools from either Cygwin or MSYS, but you need to compile and link with the compilers and libraries from MinGW.
Cygwin's gcc produces binaries that live in a unix-emulation on top of windows, and depend on a cygwin dll to act as a translator. MinGW's gcc produces native windows binaries.
