  * pass unrecognised options before the command name to the command
  Previously, options before the command name other than --help were
  just ignored, which is quite confusing behaviour.  So now,
  
  ./setup --with-compiler=ghc-6.4.2 configure
  
  works as you expect, instead of ignoring the --with-compiler option.

    M ./Distribution/Setup.hs -2 +2
