Re: Q: language-c upstream repo

Hi Ivan,

Indeed, "darcs convert" is sensitive to patch ordering, which is a
problem in your case.

I know it's not really solving the problem but have you noticed that
the user "visq" on hub.darcs.net is actually the maintainer of
language-c ? (As I can see from the repo history
http://code.haskell.org/language-c/_darcs/inventory ).  I guess you
can make patches against the hub.darcs.net repo then.
