From 694ef54978f382507a5127ce66da7770929ba2c2 Mon Sep 17 00:00:00 2001 From: Jeff Darcy Date: Wed, 7 Sep 2011 20:03:24 -0400 Subject: Eliminate many "var set but not used" warnings with newer gcc. This fixes ~200 such warnings, but leaves three categories untouched. (1) Rpcgen code. (2) Macros which set variables in the outer (calling function) scope. (3) Variables which are set via function calls which may have side effects.
