can't link postgresql-libpq on windows

i follow the instructions here: https://github.com/hdbc/hdbc-postgresql/wiki/WindowsInstall

and when cabal tries to link, i get:

Loading package postgresql-libpq-0.8.2.1 ... ghc.exe: Unknown PEi386 section name `.idata$4' (while processing: c:/PROGRA~2/POSTGR~1/9.1/lib\libpq.a)
ghc.exe: panic! (the 'impossible' happened)
  (GHC version 7.4.1 for i386-unknown-mingw32):
        loadArchive "c:/PROGRA~2/POSTGR~1/9.1/lib\\libpq.a": failed

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
