[Haskell-cafe] Hdevtools cabal support

[Maxim Kulkin]

Thanks for the support Joey!

Could you send me the full list of GHC options that your application is
built with. You can do that by issuing "cabal build -v" and then finding
options that you ghc is run with. I do not need list of your modules or
your defines though. That would help.

This is one downside of using all GHC options. I have already done
workaround for -Werror and seems like there are other situations that cause
problems (looks like CPP warnings for some reason cause preprocessing fail).
