When I compiled ghcjs-base with ghcjs-0.2.0.9006021_ghc-7.10.3 from http://ghcjs.tolysz.org/lts-6.21-9006021.tar.gz, ghcjs gave the following warnings.

The warnings are sorted.

The specialise errors are erroneously reported and it's an upstream ghc issue - https://ghc.haskell.org/trac/ghc/ticket/10721

It seems like the overlapping type family instance warnings are very old upstream ghc issues - https://ghc.haskell.org/trac/ghc/ticket/4259

The only one that seems like some amount of work is Attoparsec's Number module (which suggests using scientific instead)
