Windows build failures in FD.hs

[Edsko de Vries]

Hi all,

I'm still trying to get a Windows build (Win 7, tried both 32-bit and
64-bit, same result) -- using THREADS=1. When running 'sh validate',
compilation eventually stops with

"inplace/bin/ghc-stage1.exe" -hisuf hi -osuf  o -hcsuf hc -static
-H32m -O -Werror -Wall -H64m -O0    -package-name base-4.7.0.0

Since nobody else seems to be experiencing this, there must be
something wrong with my setup? I've tried to follow
http://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows best
I could, but I'm not a Windows user so I might have got something
wrong.

Any suggestions welcome!
