I would like to request an official, binding interpretation from the
WG15 concerning the following point in ISO/IEC 9945-2:1993 (POSIX.2).
It is unclear what the exact behaviour is when a file is added to 
an archive and only the -r option is specified in the ar utility.

First, Section 6.1.3, lines 55-57, page 662  states:
  -v  Give verbose output. When used with the option characters -d,
      -r, or -x, write a detailed file-by-file description of the archive
      creation and maintenance activity, as described in

This seems to imply that when using the -x, -d and -r options, that the verbose
output is displayed only when -v is also specified.

This implication seems to be true since all the descriptions in Section
specify the use the "-v" option except for one, on line 118, which states:
   If file is being added to the archive with the -r option, the standare
   output format shall be ...

It seems odd that line 118 should be the only description in all of
Section that does not specify the -v option.
Its unclear if the wording on line 114, which does specify the -v option,
should be continued to be used on line 118.

Further, except for line 118, section has consistently described
historical behaviour.

I would like an interpretation stating that the format specified
on line 120 is only required when -r and -v are both specified.

Thank you for your attention to this matter.

WG15 response for 9945-2:1993

The standard is unclear on this issue, and no conformance distinction can
be made between alternative implementations based on this.  This is being
referred to the sponsor.
