Thanks! :-)

Did you add the "-C" switch to "wc", too ?

It seems that "-s" disables all error output when "-p" is used.
Example (running this as plain user where "/usr" is non-empty and
readonly):
-- snip --
$ /usr/bin/rmdir -s /usr
/usr/bin/rmdir: directory "/usr": Search or write permission needed
$ /usr/bin/rmdir -s -p /usr                                           
$ /usr/bin/rmdir -p /usr                                              
/usr/bin/rmdir: directory "/usr": /usr not removed; Permission denied
$ /usr/bin/rmdir -s /usr/blabla_does_not_exist                        
/usr/bin/rmdir: directory "/usr/blabla_does_not_exist": Directory does
not exist
$ /usr/bin/rmdir -s -p /usr/blabla_does_not_exist                     
$ /usr/bin/rmdir -p /usr/blabla_does_not_exist                        
/usr/bin/rmdir: directory "/usr/blabla_does_not_exist":
/usr/blabla_does_not_exist not removed; No such file or directory
-- snip --

BTW: The source for the Solaris version of "rmdir" can be found at
http://cvs.opensolaris.org/source/xref/on/usr/src/cmd/rmdir/ and a
manual page from Solaris 9 at
http://docs.sun.com/app/docs/doc/817-0689/6mgfkpd2e?a=view#indexterm-686
