repa 3.2.3.3 compilation failure with GHC 7.8

[Rob Stewart]

Using GHC 7.8 RC1. Two build-depends entries need to be relaxed, for base and template-haskell:

  Build-Depends: 

        base                 == 4.6.* || == 4.7.*,

        ghc-prim             == 0.3.*,

        vector               == 0.10.*,

        bytestring           == 0.10.*,

        template-haskell     == 2.8.* || == 2.9.*,

        QuickCheck           >= 2.3 && < 2.7

Here's the error:
