First, the PCON register is not supported in gpsim. The good news is I
just added it and will try to get a 0.20.10 out within 24hrs with the
change. gpsim doesn't fully simulate the reset conditions, so the POR
and BOR bits will essentially be general purpose bits. (Upon startup,
both bits will be cleared. After a reset, they'll also [improperly] be
cleared).
I'm going to try to get an RPM built to simplify the install problems
everyone is having with gpsim.
