Subject: [PATCH] {gcc6,gcc6Stdenv,gfortran6,gcj}: drop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This release branch is 8½ years old and hasn’t received an update
in 6 years. Nothing in the Nixpkgs tree uses it. We can simplify a
lot of logic in the GCC and cc-wrapper derivations by removing this
unsupported version.
