Change 133684 by imp at imp_lighthouse on 2008/01/19 23:01:26

	Remove my hack, and the stray .set at which was the real problem.
	Juli suggested that I didn't want to do my hack because at would
	be corrupted potentially by the assembler using it.  She
	suggested I wanted to use the whole thing as 'set noat'.
