compile failures with base < 4.8

The .cabal files specifies compatibility with base >= 4, however, when compiling with base-4.7 or older, build failures as below occur.

I've already revised the meta-data for the affected releases:

So there's no immediate action needed. For the next release of mwc-probability it would be great if it either restores compatibility with base < 4.8, or comes with a lower bound base >= 4.8. If you want to test your package against all versions of base announced in the .cabal file, you can e.g. use https://github.com/hvr/multi-ghc-travis.

If you have any questions, please feel free to ask me!
