I was just trying to compile a package using ghc-6.3.3 and came up against a problem with the '--version'flag. Specifically, I don't think that 'ghc-6.3.3 --version' doesn't report the version to stdout. # ghc-6.3.3 --version > conftest # cat conftest [conftest is empty] #ghc-6.2 --version > conftest # cat conftest The Glorious Glasgow Haskell Compilation System, version 6.2.2 I've looked through ghc/compiler/main/DriverFlags.hs, but both older and newer versions seem to report --version through stdout, so I'm not sure where the problem is. - Alson
