From 23c4ace526fe9c5f9a4b1b0759cb76a285052ba0 Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Fri, 16 Oct 2009 15:52:06 -0700 Subject: dtc: Set "noinput" in the lexer to avoid an unused function Regenerate the corresponding generated lexer. Regenerating the lexer with current flex also provides prototypes for various yy* functions, making some -Wmissing-prototypes warnings go away as well.
