cabal-1.6.0.1 won't build with ghc-6.6.1 in WinXP

[Alistair Bayley]

I'm trying to build cabal-1.6.0.1 with ghc-6.6.1 on WinXP. "setup -v
configure" fails with this output:

Any clues as to what might be wrong? There are no buildinfo files
produced, so I can't just ignore and proceed with setup build.
