testing cabal-install-0.25.2 with ghc-7.6.1

Hi, I managed to build cabal-install-0.25.2 (from the cabal-1.16 branch) with ghc-7.6.1 Cabal. However the use of viewAsFieldDescr in cabal-install/Distribution/Client/Config.hs causes problems due to the: error "Command.optionToFieldDescr: feature not implemented" in Cabal-1.16.0, so I am not able to use cabal-install yet: $ cabal install cabal: Command.optionToFieldDescr: feature not implemented Jens
