A bunch of version bumps and minor associated
fixes - in part motivated by GHC 9 compatibility.

  * support QuickCheck 2.14
  
  Need to make the Test.QuickCheck imports explicit in
  one place because chooseAny was added as a new export
  from Test.QuickCheck in 2.14, so the import from
  Test.QuickCheck.Gen becomes redundant and causes a
  warning.

I tried building the head with

> cabal-3.4 update && cabal-3.4 build -w ghc-9.0.1

but it fails when compiling the dependencies:

dist/build/Text/Regex.o, dist/build/Text/Regex.dyn_o )

Yep - see https://hub.darcs.net/shelarcy/regex-compat-tdfa/issue/2

(I mentioned this in patch2172 but not here, sorry)

I've got a patch and also tried emailing the maintainer, no reply so
far. Next step after waiting a bit would be to ask the Hackage Trusteers
to do a non-maintainer upload or similar - or just inline the code
ourselves, it's only one file.

Ah, you already sent a fix for this issue
(https://hub.darcs.net/shelarcy/regex-compat-tdfa/issue/3).

BTW, I find it strange that we now get warnings from ghc because
something *will* be deprecated in the future. Should we add
-Wno-star-is-type to our ghc-options?

I like to build with -fwarn-as-error and this patch allows me to do that
with ghc-9.0.

  * darcs.cabal: add -Wno-star-is-type for ghc >= 9.0.1

(Perhaps i should not have sent my patch to this bundle.)

I was meaning to ask if you are okay with this before pushing to 
screened.

-Wno-star-is-type is fine with me for now, though I would rather "get with
the program" and update our code to use Type at some point. And no problem
with lumping it in this bundle.

Okay, I screened the patch. Agreed we should convert our code at some
point and then get rid of the extra option.

All fine, though

>   * tests: fix warning with GHC 9.0

feels a bit kludgy. Okay for now.

Reminds me of the preceding comment:

  -- TODO this check doesn't work at the moment - try to enable it and
see if it makes
  -- sense to keep or not.

I'd be interested: why does it not work? does it fail? can you give an
example?

Accepted, including my own follow-up patch.
