 The patch is this one.  Ian, please merge to 6.8 branch.

   * Fix nasty recompilation bug in MkIface.computeChangedOccs

 MERGE to 6.8 branch

   In computeChangedOccs we look up the old version of a Name.
   But a WiredIn Name doesn't have an old version, because WiredIn things
   don't appear in interface files at all.

   Result: ghc-6.9: panic! (the 'impossible' happened)
 (GHC version 6.9 for x86_64-unknown-linux):
 lookupVers1 base:GHC.Prim chr#{v}

   This fixes the problem.  The patch should merge easily onto the branch.

 When rebuilding the base package you might encounter this:

 {{{
 ../../compiler/stage1/ghc-inplace -package-name base-3.0.1.0 -hide-all-
 packages -split-objs -i -idist/build/autogen -idist/build -i. -Idist/build
 -Iinclude -#include HsBase.h -odir dist/build -hidir dist/build -stubdir
 dist/build -package rts-1.0 -O -fglasgow-exts -package-name base -XCPP

 Data/Generics/Twins.hs -o dist/build/Data/Generics/Twins.o  -ohi
 dist/build/Data/Generics/Twins.hi
 ghc-6.8.2: panic! (the 'impossible' happened)
   (GHC version 6.8.2 for powerpc-apple-darwin):
 lookupVers1 base:GHC.Prim sym{tc}
 }}}

 Workaround is to clean in `libraries/base`.

 The problem is that `MkIface.computeChangedOccs` needs to avoid wired-in
 names when checking version numbers, because wired-in names are never
 mentioned in usages.

 I believe simonpj has a patch for this in his working tree, we diagnosed
 it before disappearing for the Christmas period.
