    Problem Text
    This test will fail on implementations that treat the use of ^
    as an anchor as an error when used with expr in a regular
    expression match statement.

    test 77 runs

    expr '^bc' : '^^'

    and expects the output to be

    0

    Our expr outputs 1. This is allowable because the
    standard says

    "...all patterns are anchored to be beginning of the string
    (...) and, therefore, it is unspecified whether ^ is a special
    character in this context."
