C3 and I forgot...

how to code in C. Below the program blinks the LED but I do not get the - printf("Starting blinky\n"); to show on the terminal screen. I am working in project view. When I remove the 'auto sd_mount' stuff, then I get "Starting blinky" on the terminal screen, in all memory modes. Must be something really dumb that I am doing.
Thanks

void high(int pin) // high function definition
{
int mask = 1 << pin; // Set up mask
OUTA |= mask; // Bitwise OR w/ OUTA & DIRA
DIRA |= mask;
}
void low(int pin) // low function definition
{
int mask = 1 << pin; // Set up mask
OUTA &= ~mask; // Pin output state to low
DIRA |= mask; // Pin direction to output
}
int main(void)
{
sleep(1);
printf("Starting blinky\n");
while(1)
{
high(23);
sleep(1);
low(23);
sleep(1);
}
return 0;
}

I remember the C3 SD card is different. It's on a shared SPI bus.....ok, I forgot the details beyond this. Check the C3 docs and in PropGCC are their especial C3 demo programs for some functions?
