GHC CVS Green-card failure

| c:\cvs\fptools\ghc\compiler\ghc.exe: panic! (the `impossible'
happened, GHC
| version 5.05):
|         Ix{Int}.index: Index (131330) out of range ((0,161))

This is invariably as a result of GHC trying to read an old interface
file, in a different format.  It's unfortunate that duff interface files
give rise to such a weird outcome.

Solution is easy: rm *.hi; make
