Use U+2018 instead of U+201B quote mark in compiler messages

This matches GCC's choice of Unicode quotation marks (i.e. U+2018 and U+2019)
and therefore looks more familiar on the console. This addresses #2507.

       use a standalone 'deriving instance' declaration,
         so you can specify the instance context yourself
