[Haskell-cafe] 1-to-many preprocessor in stack/Cabal builds

[Edward Z. Yang]

Hello Andrey,

I do not know what the right way to sovle your problem is, but if it is
indeed the case that this cannot be done with Cabal, speaking as a Cabal
developer, we definitely should try to fix this.  A bug report
would be much appreciated.

I'm pretty sure this message comes from Stack; src/Stack/Types/Package.hs.

Cheers,
Edward
