    Problem Text
    The freopen tests are depending on a specific ordering of ".o" files
    in the link load of two binaries which have multiply defined variables.
    If the module freopen1.o is before freopen.o in the link order the
    the resolution of references is correct and the tests pass.

    The usage in VSX violates the C Standard. From 3.7 of ANSI
    C (External Definitions):

    An external identifier is an external declaration that is also a
    definition of a function or an object. If an identifier declared
    with external linkage is used in an expression (other than as the
    operand of a sizeof operator), somewhere in the entire program
    there shall be exactly one external definition for the identifier;
    otherwise, there shall be no more than one.

    The declarations in freopen.c should use the 'extern' storage-class
    specifier.

    Review Information

    Review Type TSMA Review
    Start Date null
    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    It is accepted that this is a test suite fault. The current test code
    does not conform to the Strict Ref/Def model required by ANSI C, though
    most compilers allow a Relaxed Ref/Def model and will accept the current
    test suite code. It is recommended that this recognised as a test suite
    deficiency.

    Review Type SA Review
    Start Date null
    Completed null
    Status Complete
    Review Resolution Test Suite Deficiency (TSD)
    Review Conclusion
    This is an agreed Test Suite Deficiency.
