    Problem Summary TSD4U.00130 This test may fail on implementations which do not support setting the S_ISUID and S_ISGID mode bits via an open(O_CREAT) call.
    Problem Text
    In the setup for both of these testcases creat is used to create a
    file. An attempt is made to create these files with the S_ISUID and
    S_ISGID bits set.
    creat() (open() with O_CREAT) is only permitted to set file permission
    bits. According to X/Open System Interfaces and Headers Issue 4,
    Version 2, under open(), O_CREAT:
    "... Thus, all bits in the file mode whose corresponding bit in the
    file mode creation mask is set are cleared. When bits other than the
    file permission bits are set, the effect is unspecified. ..."
    Under sys/stat.h:
    "Implementations may OR other implementation-dependent bits into
    S_IRWXU, S_IRWXG, and S_IRWXO, but they will not overlap any of the
    other bits defined in this document. The file permission bits are
    defined to be those corresponding to the bitwise inclusive OR of
    S_IRWXU, S_IRWXG, and S_IRWXO."

    The meaning of other bits is implementation-dependent. S_ISUID and
    S_ISGID are *NOT* permission bits according to the way the spec is
    currently worded.

    The test suite cannot expect an implementation to set the S_ISUID
    and S_ISGID bits on an open/creat call, because the spec does not
    define these bits as permission bits.

    Test Output
    TEST CASE: fchown

    TEST PURPOSE #3
    A call to int fchown(int fildes, uid_t
    owner, gid_t group) when fildes refers to a regular
    file and the call is made by a process without
    appropriate privileges shall clear the S_ISUID and
    S_ISGID bits of the file mode.
    PREP: Create test file
    PREP: Make sure bits are set
    ERROR: Bits not set (st_mode=0300000777)
    3 FAIL

    TEST CASE: lchown

    TEST PURPOSE #4
    A call to int lchown(const char *path,
    uid_t owner, gid_t group) when path refers to a
    regular file and the call is made by a process without
    appropriate privileges shall clear the S_ISUID and
    S_ISGID bits of the file mode.
