| Excellent!  Now I get much fewer failures.

|
| from validate:
| Unexpected failures:
|     equal(normal)
|     process006(normal)
|     set(normal)
|     simpl014(normal)
|     tc(normal)
|     termination(normal)
|     while(normal)
|
| from testing equal:
| =====> equal(normal)
| cd . && '/Users/me/modified/ghcvaltest/compiler/stage2/ghc-inplace'
| -no-recomp -dcore-lint -dcmm-lint -Di386_unknown_linux
| -dno-debug-output -c equal.hs    >equal.comp.stderr 2>&1
| Compile failed (status 256) errors were:
| ghc-6.9.20080603: panic! (the 'impossible' happened)
|    (GHC version 6.9.20080603 for i386-unknown-linux):
|         ASSERT failed! file typecheck/TcMType.lhs line 520 t_aeQ{tv} [tau]
|
| Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
