  * FIX #2521: trailing colon in GHC_PACKAGE_PATH
  This was broken in the System.FilePath switchover, since filepath's
  splitSearchPath doesn't do what we want (it ignores empty
  components on Windows, and treats them as "." on Unix).  So we use our
  own hand-rolled version, just like GHC.

    M ./utils/ghc-pkg/Main.hs -1 +21
