Wow, thanks.  Should I change all of the references to unsigned int, e.g.

volatile unsigned char *start, *LED;

and cast to unsigned char here  
start = (unsigned char *)mmap(0, getpagesize(), PROT_READ|PROT_WRITE, 
MAP_SHARED, fd, 0xE8000000);

and here?
LED = (unsigned char *)(start + 0x8);

Thanks super,
Craig
