Andrew,

This change is breaking the binutils build for me.  The build dies with:

/scratch/sellcey/repos/objcopy/src/binutils/binutils/objcopy.c: In function 'init_section_add':
/scratch/sellcey/repos/objcopy/src/binutils/binutils/objcopy.c:3556:31: error: declaration of 'optarg' shadows a global declaration [-Werror=shadow]
cc1: all warnings being treated as errors

optarg is defined as a global variable in include/getopt.h in the binutils
sources.  Could you rename the optarg argument to something else?  I am not
sure if other people are seeing this or not, I am building binutils on ubuntu 12.04
with GCC 4.6.3.
