New description:

 Windows
 GHC 6.10.4
 Cabal 0.6.2
 cabal-install 0.6.2

 During configure, I think cabal-install is testing for the existence of
 various libraries by compiling empty "main() {}" C sources. But the
 command it constructs to do the compile contains -Wno-attributes, which
 gcc 3.4.5 doesn't understand.

Comment:

 Improving the formatting of this report and increasing the severity to
 major because it is, I believe, blocking the installation of software that
 would otherwise work.
