Test Name: chmod.7 Failed

	Test Description:
A call to chmod(path, mode) from a process without appropriate
privileges when the group owner of the regular file specified by path
does not match the effective group ID or one of the supplementary
group IDs shall clear the S_ISGID bit upon successful completion.
Posix Ref: Component CHMOD Assertion 5.6.4.2-29(A)

	Test Strategy:
VERIFY that process has suitable privileges
DETERMINE whether chmod() with appropriate privileges is permitted
from the environment variable VSX_PRIV_CHOWN_SUPP
ASSIGN the current process appropriate privileges using setprv() -
vport
DETERMINE whether setting S_ISUID and S_ISGID is permitted form the
environment variable VSX_SET_ID_MODES_SUPP
VERIFY that vsxg1 is not a supplementary group for this process
CREATE child process using cppair()
  SET effective group id to actual group id using setgid() and
  getegid()
  VERIFY that the effective and actual group ids are the same using
  getgid() and getegid()
  SET effective user id to actual user id using setuid() and geteuid()
  VERIFY that the effective and actual user ids are the same using
  getuid() and geteuid()
  REMOVE the CHOWN and SETID privileges from the current process using
  unsetprv()
  VERIFY that unsetprv() returned 0
  CREATE two files with all access modes available and S_ISGID set
CREATE child process using cppair()
  SET and VERIFY that the effective user and group ids are vsx1/vsxg1
  REMOVE the CHOWN and SETID privileges from the current process using
  unsetprv()
  FOR each file with mode excluding and including S_ISGID
    CHANGE the mode of the file using chmod() with the current file
    mode
    VERIFY that chmod() returned 0
    OBTAIN file status information for file using stat()
    VERIFY that the file status mode has the expected value

successful call to chmod(&quot;chmod-t.7b&quot;, 02770) did not change mode of
	file correctly
expected: 0770, observed: 02770

&lt;/pre&gt;
