From b1c1949e60e7c61bcd9f40f712d07494596491b2 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 26 Mar 2010 09:16:21 -0700 Subject: Don't take the address of a void object. GCC 4.5 warns about "extern void _end; &end;". Use char[] instead, as that also doesn't fall foul of a target's .sdata optimizations.
