non-UNIX POSIX?

What existing major operating systems are likely to have difficulty becoming
fully POSIX compliant? What are the reasons given for such difficulties?

If federal agencies are going to require C2 security by Jan 1, 1992, and
POSIX systems will not be certified until probably early 1991 due to no labs
accredited to certify  until late 1990, then do we have less than one year
of FIPS 151-1 before we have to require vendors to recertify a C2 capability
and the requirement that FIPS 151-1 undergo major changes to accomodate the
security issues not now addressed?
