Hi all, Attached are some patches for the extensible-exceptions library, which lets packages use the new exceptions API portably on all versions of ghc (well, at least as far back as 6.6.1, from my tests). To summarize: I filled out the API by copying all of the missing functions from base4:Control.Exception, and edited the .cabal file to make 'cabal install extensible-exceptions' do the right thing. Also, I'm eager to have this package on hackage so that I can start using it in my own libraries; let me know if there's anything else I could do to work towards that goal.

M ./Control/Exception/Extensible.hs -1 +1 Sat Nov 15 10:52:57 PST 2008 Judah Jacobson * Use Cabal flags to select which version of Control.Exception to build on top of. This ensures that cabal-install will use the correct version of base. M ./Control/Exception/Extensible.hs -1 +1 M ./extensible-exceptions.cabal -1 +5
