(delay 1 ...) vs (delay (const 1) ...) won't make a difference. They are 
identical.

However, It seems that CGEN generating SID expects a different syntax 
for delay than CGEN generating SIM.

CGEN generating sid expects

    (set (delay 1 pc) retaddr)

while CGEN generating SIM expects

    (delay 1 (set pc retaddr))

I do recall the new syntax being introduced some time ago, however, I 
don't recall that the old syntax was depricated. Does anyone know if 
both are still supposed to work?
