Greetings all, from a noobie.

I have just discovered darcs, looks impressive.

On a fresh 'get' of darcs, I get the following compile warnings:

Patch.lhs:114:
    Warning: No explicit method nor default method for `coarbitrary'
             In the instance declaration for `Arbitrary Patch'

Patch.lhs:243:
    Warning: No explicit method nor default method for `coarbitrary'
             In the instance declaration for `Arbitrary PatchInfo'

Patch.lhs:245:
    Warning: No explicit method nor default method for `coarbitrary'
             In the instance declaration for `Arbitrary PackedString'

Patch.lhs:286:
    Warning: No explicit method nor default method for `coarbitrary'
             In the instance declaration for `Arbitrary Char'


The unit tests pass, but is this (known|a problem|a bug|ignorable)?


$ darcs --version
0.9.15pre
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.0.1
$ gcc --version
gcc-3.2.2 (GCC) 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk)


Thanks for your attention
	Nigel
