   gcc will output
   
                   increment low 32bit
                   if zero
                           increment high
   
   Which means we can rapidly get 2^32 out of sync
   
True and this equals the "fix" suggested C code involving
two 32-bit counters that the original author posted :-)

So this makes both cases equally wrong.
