gpsim - The gnupic Simulator

I'm attempting to simulate an example from "PIC In
Practice" (new edition). This is a straightforward
example that uses TMR0 to implement a 1 second delay,
by setting the prescaler to 256 (with a 32KHz
crystal), and waiting for TMR0 to reach 32. This
doesn't work in GPSIM, because TMR0 does not seem to
increment with each instruction, so the code gets
stuck in the timer loop..
