/* This is a cc optimiser bug for ultrix 4.3, mips CPU.
 | 
						|
 * What happens is that the compiler, due to the (a)&7,
 | 
						|
 * does
 | 
						|
 * i=a&7;
 | 
						|
 * i--;
 | 
						|
 * i*=4;
 | 
						|
 * Then uses i as the offset into a jump table.
 | 
						|
 * The problem is that a value of 0 generates an offset of
 | 
						|
 * 0xfffffffc.
