Extended Description

I got this today:

CGDecl.cpp:85:8: error: duplicate case value '6'
case Decl::Label: // label x;
^
CGDecl.cpp:73:8: note: previous case defined here
case Decl::Label:
^

It should say "duplicate case value 'Decl::Label'"

Fixed by a patch from Terry Long, committed as r156904.
