No progress at all so far.  According to the ticket there is a working 
mingw port now:

http://hackage.haskell.org/trac/ghc/ticket/1884

There is apparently support for Win64 in libffi (not sure if this patch 
has been merged or not):

So the main remaining difficulty would be implementing the Win64 C call 
ABI in the native code generator.
