if you follow those steps, but then don't override the host in the ./configure step to just let it pick up the cygwin environment will it work properly?

No:

Configuring extensible-exceptions-0.1.0.0... cabal-bin.exe: Cannot find the program 'ghc' at '/c/bin/ghc-6.10.1.20090308/bin/ghc' or on the path

'ldd libraries/cabal-bin.exe' finds no cygwin dependencies; everything points to /c/WINDOWS/system32. I presume that the mingw-ghc used the include mingw gcc, not cygwin's gcc. Indeed, I tried deleting that file, and got:

ghc.exe: could not execute: C:\bin\ghc-6.10.1.20090308\gcc

It doesn't seem like it will build cygwin programs.

There's no fundamental reason why there can't be a "real" Cygwin GHC (that is, a GHC producing binaries that are linked against the Cygwin DLL). Indeed it used to work, a long time ago. But due to lack of demand it bitrotted. I imagine it would be a fair amount of work to get it going again, but of greater concern to me is how we would *keep* it working: there needs to be interested people actively maintaining buildbots and catching bitrot as it happens. Without a sustainable process, there isn't a great deal of point in updating the port. Cheers, Simon
