cvs-1.11 and Sun Solaris 2.7

[Nelson H. F. Beebe]

I built cvs-1.11 on about 10 UNIX flavors over the weekend, using the
canonical

        ./configure && make all check install

Most succeeded.  However, on Sun Solaris 2.7, the check failed like
this:

        % make check
        ...
        /bin/sh ./sanity.sh `pwd`/cvs
        This test should produce no other output than this line, and a final 
"OK".
        id: illegal option -- u
        Usage: id [user]
               id -a [user]
        Notice: The default version of id is defective, using
        /usr/local/bin/gid instead.
        lid: invalid option -- u
        Try `lid --help' for more information.
        expr: RE error
        Test suite does not work correctly when run by a username
        containing regular expression meta-characters.
        make[1]: *** [check] Error 1

Indeed, compare the behavior of id on various systems:

Apple Macintosh GNU/Linux 2.2.15pre9:
        % /usr/bin/id -a
        uid=607(beebe) gid=607(beebe) groups=607(beebe),100(users)
        % /usr/bin/id -u beebe
        607

Compaq/DEC Alpha OSF/1 4.0:
        /usr/ucb/id -a
        usage: id  [user]
               id  -G [-n] [user]
               id  -g [-nr] [user]
               id  -u [-nr] [user]
        /usr/ucb/id -u beebe
        887

               id  -g [-nr] [user]
