[Dune] gcc 4.8.3 & decay_t ?

[Christian Engwer]

Dear Benedikt

you are runnning the trunk fr the trunk g++-4.8 is not supported
anymore for several reasons.

At the DUNE-DEV-Meeting in HD we decided the followng:

  gcc-4.9 will be the target compiler for the 3.0 release. C++11 is
  completely allowed, experimental C++14 features in gcc-4.9, too!
  Clang 3.5 is definitely C++14 compliant. ICC >= 15.1 should be
  supported.
