    Revert "Remove the Windows GCC driver."
    
    This reverts commit d6cecde585b0980ed8e0050c5a1d315789fb6356.
    
    The patch broke Simon PJ's Windows build, becuase he didn't
    have (and should not need) a separate msys2 gcc.
    
    Following an exchange on the ghc-devs list, Tamar wrote
    
      Oops, sorry, didn’t notice it because both mine and harbormaster’s
      msys2 have separate GCCs installed as well.
    
      I don’t see an easy fix that would also work for end user Configure
      based cabal installs. So I think I’ll have to go back to the drawing
      board for this one.
    
      You can just leave it reverted.
