+Cygwin, kindly provided by Claus Reinke. It does not discuss alternative

+<programlisting>- Install some editor (vim, emacs, whatever)
+
+- Install cygwin (http://www.cygwin.com)
+ ; i used 1.5.16-1, installed in c:\cygwin
+ - run 'setup.exe'
+ Choose a Download Source:
+ select 'download from internet';
+ Select Root Install Directory:
+ root dir: c:\cygwin;
+ install for: all users;
+ default file type: unix
+ Select Local Package Directory
+ choose a spare temporary home
+ Select Your Internet Connection
+ Use IE5 settings
+ Choose a Download Site
+ Choose your preferred main mirror and
+ Add 'http://www.haskell.org/ghc/cygwin'
+ Select Packages
+ In addition to 'Base' (default install),
+ select 'Devel->ghc-depends'
+
+- Install mingw (http://www.mingw.org/)
+ ; i used MinGW-3.1.0-1.exe
+ ; installed in c:\mingw
+ - you probably want to add GLUT
+ ; (http://www.xmission.com/~nate/glut.html)
+ ; i used glut-3.7.3-mingw32.tar
+
+- Get recent binary snapshot of ghc-6.4.1 for mingw
+ ; (http://www.haskell.org/ghc/dist/stable/dist/)
+ - unpack in c:/ghc
+ - add C:\ghc\ghc-6.4.1\bin to %PATH%
+ (Start->Control Panel->System->Advanced->Environment Variables)
+
+- Get cvs version of ghc
+ ; also, subscribe to cvs-all@haskell.org, or follow the mailing list
+ ; archive, in case you checkout a version with problems
+ ; http://www.haskell.org//pipermail/cvs-all/
+ - mkdir c:/fptools; cd c:/fptools
+ ; (or whereever you want your cvs tree to be)
+ - export CVSROOT=:pserver:anoncvs@cvs.haskell.org:/cvs
+ - cvs login
+ ; pw: cvs
+ - cvs checkout fpconfig
+ - cd fptools
+ - cvs checkout ghc hslibs libraries
+
+- Build ghc, using cygwin and mingw, targetting mingw
+ - export PATH=/cygdrive/c/ghc/ghc-6.4.1:$PATH
+ ; for haddock, alex, happy (*)
+ - export PATH=/cygdrive/c/mingw/bin:$PATH
+ ; without, we pick up some cygwin tools at best!
+ - cd c:/fptools/fptools
+ ; (if you aren't there already)
+ - autoreconf
+ - ./configure --host=i386-unknown-mingw32 --with-gcc=C:/Mingw/bin/gcc.exe
+ ; we use cygwin, but build for windows
+ - cp mk/build.mk.sample mk/build.mk
+ - in mk/build.mk:
+ add line: SplitObjs = NO
+ (MSYS seems slow when there are zillions of object files)
+ uncomment line: BuildFlavour = perf
+ (or BuildFlavour = devel, if you are doing development)
+ add line: BIN_DIST=1
+ - make 2>&1 | tee make.log
+ ; always useful to have a log around
+
+- Package up binary distribution
+ - make binary-dist Project=Ghc 2>&1 | tee make-bin-dist.log
+ ; always useful to have a log around
+ - cd ghc-6.5
+ - chmod +x ../distrib/prep-bin-dist-mingw
+ ; if you're happy with the script's contents (*)
+ - ../distrib/prep-bin-dist-mingw
+ ; then tar up, unpack where wanted, and enjoy</programlisting>
