Branch: MAIN
Changes since 1.32: +26 -122 lines
Remove outdated bits for <ghc-6.10 and <cabal-1.8. Switch from 'eerror' to 'eqawarn' as suggested by PaweĊ‚ Hajdan, Jr. (http://www.gossamer-threads.com/lists/gentoo/dev/251259). Install empty '.conf' files for binaries to help 'haskell-updater' pick binaries built with onder haskell toolchain on ghc upgrade.
