There will be a major change in primops pushed into HEAD, hopefully with next 24 hours. This change breaks backwards compatibility for comparison primops and ONCE IT IS PUSHED will require you to:
1) Upgrade to latest versions of Alex and Happy (cabal update && cabal install alex happy). These versions are not yet available. When they are DO NOT INSTALL THEM UNTIL CHANGES ARE PUSHED INTO HEAD.
2) Blow away your build. Be sure to run ./configure to pick up new versions of Alex and Happy
3) Rebase your branches on top of HEAD, if these branches were in a repository affected by primop change. Repositories that will be affected: GHC, testsuite, array, base, dph, ghc-prim, integer-gmp, integer-simple, primitive, template-haskell.

Does point #1 mean that these versions of alex and happy are not backwards compatible, i.e., that they generate code that is only compatible with the very latest, new-primop, version of ghc that you are about to push? That seems like it would be a bad situation to be in... Geoff
