How portable is this? SUSv2 seems to imply that n==0 would result in
undefined behavior, so this may not work without being compliant with
C99. There are some strange targets that wpa_supplicant is used on, so
I'm not sure whether there would be enough justification for this change
if there is risk of breaking debugging on such platforms.
