ghc-4.03 on cynwin deriving oddity.

[Alex Ferguson]

Observe:


BASH.EXE-2.02$ cat Enum.hs

enumerate :: (Enum a, Bounded a) => [a]
enumerate = [minBound .. maxBound]

data Test = Foo | Bar | Blah | Nonsense
            deriving (Show, Enum, Bounded)

main = print (enumerate :: [Test])
BASH.EXE-2.02$ ghc-4.03 -static Enum.o
BASH.EXE-2.02$ ./a.exe
[Foo,Foo,Foo,Foo]


Whereas, with ghc-4.02, under Solaris 2.5:

yeats.ucc.ie:~/LVO: a.out
[Foo,Bar,Blah,Nonsense]


What, as they say, gives?

Cheers,
Alex.
