Head badly broken

>From a clean build of HEAD, I’m getting tons of failures like this

T5490.hs:19:22: error:

    Illegal symbol '.' in type

    Perhaps you meant to write 'forall <tvs>. <type>'?


19 |                | ∀ e . Exception e ⇒ Failure e

   |                      ^
This is in typecheck/should_compile
Then I also get errors in things like typecheck/should_fail/tcfail190, where the output differs from the .stderr file in by the presence of bullets in GHC’s output. The bullets seem to be missing from the tcfail190.stderr file.
This is really painful.  I can’t validate.
Any ideas?
