From: "Andre W B Furtado" <andrefurtado@ieg.com.br> Is the following problem a specific cygwin problem and how can I overcome it? It happened to me while trying to invoke haddock:

/cygdrive/c/haskell/cygwin/usr/local/bin/haddock: Cannot fork: Resource temporarily unavailable

This sounds just like what I got with cygwin and Python. You have to rebase your dll's due to some upgrade/restructure they did, just search for rebase and cygwin and I'm sure you'll find some text on how to fix it. /Marcus
