From 341df2bdc3f9664587a57f947249c3208da77c9b Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 30 Apr 2010 15:27:32 +1000 Subject: [PATCH] dtc: Add -Wredundant-decls (resend) We are almost clean already with the -Wredundant-decls warning. The only exception is a declaration for isatty() inside the flex-generated code. This can be removed by using flex's "never-interactive" option, which we probably should be using anyway, since we never parse interactively in the sense that this option implies.
