I was trying to install an extension (network-2.0) to Haskell on cygwin and I got an error or warning which requested to be reported to you :) You can see the output below and if you need more info I'll be glad to provide it to you.

Please read

http://www.gnu.org/software/autoconf/manual/html_node/Present-But-Cannot-Be-...

and then show that to the maintainer of the Haskell package, who can fix this in his package. The error becomes clearer if you look at the part of the config.log file that deals with this compile failure (and maybe also some Cygwin documentation).

FWIW, these may or may not be followup errors; I don't know.
