I'm sorry, my previous posting had a glaring error which crept in as I
over-optimised my c-code.  What I should have said was:
	long *uBuf;
	uBuf = (long *) 0xa0811000;
	printf("Buffer at %X starts with %X\n",uBuf,*uBuf);

The reason is still the same.  The compiler needs the cast to know that
0xa0811000 is a pointer value.
