just curious, is there really a difference between

     #define disable_irq(n)     	\
 	do { asm ("lda #$80"); asm ("trb $fd01+"#n"*4"); } while (0)

and

     #define disable_irq(n)     	\
	{ asm ("lda #$80"); asm ("trb $fd01+"#n"*4"); } 

? i've seen the first variant a couple of times now, but always used
the second one without problems ... so is there a reason to prefer the
first? (can you show an example where the second wouldnt work?)
