/*
        first test for posix directory routines for the c64
        kludges:
        -   currently uses cbm_open, which conflicts with standard i/o,
                which in turn makes it infact kindof unuseable. this can
                be easily changed however, since the only reason not to use
                open/read was that it currently appends ,u,r to filenames
        -   the offset in current dir stream should better be calculated
                from the values returned by "read".
        -   the type flag isnt filled in atm.
        -   scandir/alphasort/versionsort is missing
        -   some bits are currently untested (ie, unused in the testprogram)
