    Problem Text
    According to VWG/003/060392, \{\} imbalance behavior is undefined for EREs
    under XPG4. Thus, the expected testcase results are incorrect. Our
    implementation treats unbalanced braces as ordinary characters.

    Also according to VWG/003/060392, "the test should be left as it is - no
    other action is required." This doesn't make sense, the testcase is
    expecting behavior not defined in XPG4, and should be changed or
    eliminated.

    Test Output

    ************************************************************************
    /tset/XPG4.os/genuts/regcomp/T.regcomp 30 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_EBRACE or REG_BADPAT.
    Otherwise:
    A call to regcomp() returns REG_ENOSYS and sets errno to ENOSYS.

    Test Strategy:
    CREATE pattern with xyab{3,}jkl{
    CALL regcomp() with pattern and cflags set to REG_EXTENDED
    VERIFY that regcomp() returned either REG_EBRACE or REG_BADPAT

    Test Information:
    regcomp(preg, "xyab{3,}jk{", REG_EXTENDED) returned 0 (No Error)
    expected 9 (REG_EBRACE) or 2 (REG_BADPAT)
