Well, since optimization is probably performed at the procedure level, and 
since there is nothing in the procedure that indicates errno changes, it is 
possible that the optimizer might make a bad choice. However, since the 
example procedure is fetching the address of errno (which won't change 
anyway) then it is unlikely that any optimization would cause a problem. 
Perhaps Carsten was simply being cautious?
