+/*
+       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)
