Ricardo,

The PGCHIP driver is not supported, and I think can be thought of as
an experiment that was never really completed.  Well at least I'm not
too sure of whether it is supposed to be working.

However, if you are still interested, the above errors look like simple
casting issues, just cast the results by inserting "(char *)" at the
appropriate places.

Best regards,
