2007-07-05 Alan Modra <amodra@bigpond.net.au>
* doc/binutils.texi (size): Document --common.
* size.c: Make a number of vars static. Delete unnecessary
function declarations.
(show_common, common_size): New vars.
(usage): Describe --common.
(OPTION_FORMAT, OPTION_RADIX, OPTION_TARGET): Define and use.
(long_options): Add common.
(calculate_common_size): New function.
(print_berkeley_format): Add common_size to bsssize.
(sysv_one_line): New function split out from..
(sysv_internal_printer): ..here.
(print_sysv_format): Handle display of *COM*.
(print_sizes): Call calculate_common_size.
2007-07-05 Alan Modra <amodra@bigpond.net.au>
* emul_aix.c (ar_emul_aix_internal): Rename "next" to "archive_next".

radices; decimal and hexadecimal for @option{-d} or @option{-x} output, or
octal and hexadecimal if you're using @option{-o}.
@item --common
Print total size of common symbols in each file. When using Berkeley
format these are included in the bss size.
@item -t
@itemx --totals
Show totals of all objects listed (Berkeley format listing mode only).
