    Problem Text

    The POSIX.2 std 1003.2-1992 Volume 1 page 84, 2.8.4.1.2 states:
    'The right parenthesis is special when matched with a preceding left
    parenthesis, both outside a bracket expression'. Therefore,
    regcomp(preg, "xy(ab))z", REG_EXTENDED) shall return 0.

    However, if the test is changed to
    regcomp(preg, "xy((ab)z", REG_EXTENDED), REG_EPAREN will be returned.

    Test Output

    /tset/XPG4.os/genuts/regcomp/T.regcomp 28 Failed

    Test Description:
    If regcomp() is supported:
    When the REG_EXTENDED flag is set in cflags, and pattern contains
    a () imbalance, then a call to regcomp(preg, pattern, cflags)
    returns either REG_EPAREN or REG_BADPAT.
    Otherwise:
    A call to regcomp() returns REG_ENOSYS and sets errno to ENOSYS.

    Test Strategy:
    CREATE pattern with xy(ab))z
    CALL regcomp() with pattern and cflags set to REG_EXTENDED
    VERIFY that regcomp() returned either REG_EPAREN or REG_BADPAT

    Test Information:
    regcomp(preg, "xy(ab))z", REG_EXTENDED) returned 0 (No Error)
    expected 8 (REG_EPAREN) or 2 (REG_BADPAT)

    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    This is accepted to be a test suite deficiency. The second of the right
    parentheses should be treated as an ordinary character since it is not
    matched by a left parenthesis. It is recommended that this be treated
    as a test suite deficiency.
