Validates failures on Mac OS X

[Manuel M T Chakravarty]

Today, I am getting 17 failures in validate:

Unexpected failures:
    2302(normal)
    2816(ghci)
    Base1(normal)
    Compose(normal)
    PList1(normal)
    PList2(normal)
    T1969(normal)
    T3294(normal)
    boxy(normal)
    ffi005(normal)
    ghci028(ghci)
    print021(ghci)
    print033(ghci)
    simpl017(normal)
    tc211(normal)
    tc214(normal)
    tcfail165(normal)

Some are space-leak tests that exceed the allowed allocation a little  
and some of complaints that predicative types are deprecated.  I  
didn't check them all, but they surely are not all platform dependent  
and should have been picked up by any validate run.
