* For m88k, we define our jmp_buf length
- * to be the size of 22 longs. <machine/setjmp.h>
+ * to be the size of 21 longs. <machine/setjmp.h>
* The buffer's usage is as follows:
*
* jmp_buf[0] return address
* jmp_buf[1] signal set (if used)
* jmp_buf[2 to 19] r14 to r31
- * jmp_buf[20] 'used' flag
- * jmp_buf[21] setjmp type
+ * jmp_buf[20] setjmp type
