    Problem Text
    This problem is being caused by getenv() being used in a non-portable
    manner in cc09es.c (iconv-d.c.9) of XPG4.hdr/misc/iconv/L.iconv. The
    test should be doing an iconv_open("IBM-939", "IBM-932") since those
    are the VSX_CODESET variables we've configured. The variables are
    obtained via two calls to getenv(), one after another. Obviously, the
    test assumes that getenv() is going to return different character
    pointers for each call. This cannot be expected according to the
    standard which states "The string pointed to shall not be modified by
    the program, but maybe overwritten by a subsequent call to the
    {getenv} function". Our implementation used the same storage for each
    return value, hence the string returned for the value for VSX_CODESET1
    was overwritten by the string returned for the VSX_CODESET2 variable.
    The string returned by the first call to getenv() must be copied to a
    safe buffer before the second call.

    We submitted a earlier waiver for getenv() being used in the same way
    and causing a set of failures in another test. This waiver was
    accepted as TSD4.182.
    Test Output
    /tset/XPG4.hdr/misc/iconv/T.iconv 9 Failed

    Test Description:
    If the header file contains a macro definition for iconv, it evaluates
    its arguments only once, fully protected by parentheses when
    necessary, and protects its return value with parentheses.

    Test Strategy:
    INVOKE iconv() macro with an increment and assignment in each
    argument.
    CAST subscripted macro to (void) - this verifies the return value is
    parenthesised.
    VERIFY that increments occurred once and assignments gave correct
    values.
