CONFORMING TO

       The Linux pcp-ipcs utility is not fully compatible to the POSIX pcp-ipcs utility.  The Linux version does
       not support the POSIX -a, -b and -o options, but does support the -l and -u options not defined by POSIX.
       A portable application shall not use the -a, -b, -o, -l, and -u options.
