Hmm, I think it introduces a bug since utime's semantics depends on 
whether the second argument is NULL or not. If it is not NULL but 
points to an uninitialized instance of struct utimbuf, utime will 
probably have some strange effects :-).

It looks like the real problem lies in the compiler, NULL is 
perfectly valid here. What warning does the compiler spit out?
