You're doing a *port* here, to create a GHC that can generate Cygwin 
binaries, using a GHC that generates MinGW binaries to bootstrap from. 
This isn't something you should expect to work out of the box :-)

For a start, you should set your platforms like this:

   build  = i386-unknown-mingw32
   host   = i386-unknown-mingw32
   target = i386-unknown-cygwin32

It looks like your stage1 compiler is crashing, but I have no idea why.

If you're really interested in getting this working, expect to have to do a 
lot of hacking in GHC's internals, build system, and libraries.  We're here 
to help, of course.

Cheers,
