$ cat /etc/release
Solaris 8 10/01 s28s_u6wos_08a SPARC

$ expr -- -1 + 2

$ expr -1 + 2

$ expr '-lfoo' : '-l\(.*\)'
foo
So Solaris bows to POSIX to discard "--", but otherwise behaves as expr(1)
has done since the dawn of time.
Open UNIX 8 behaves the same way.
Do any real implementations actually break either of the last two cases?
(I don't know how to access the GNU sh-utils CVS repository to see what Paul
Eggert's done in this regard.)
Cheers,
Mark.
