PATCH: make ar emitt a warning if an archive is created (POSIX)

[Tobias Burnus]

Hi,

this is item (c) on my `make ar POSIX conform` list:
  http://sources.redhat.com/ml/bug-binutils/2003-q4/msg00014.html
[(b) is already fixed]

>From IEEE Std 1003.1, 2003 Edition (POSIX 2001), (c) The Open Group 2003:
|    ar - create and maintain library archives
|
| The following options shall be supported:
| -c Suppress the diagnostic message that is written to standard error by
|    default when the archive archive is created.
|

Currently, ar does never write such a message. There was some support
for that, but this section is '#if 0'ed.

With best regards,

Tobias
