No. It is not Oracle: it _does_ return NULL if it is not set, and an empty string iff it is set to an empty string.

MinGW does that quite fine (actually, it just calls the MS C Runtime library; maybe they still had a clue bat back when they wrote that?).

Funnily enough, MinGW does not have gettimeofday(). Actually, for purposes of getting git to compile, I had to

	int gettimeofday(struct timeval *tv, void *tz)
	{
	        return -1;
	}

Lucky you! Fortunately, I don't have any Windows at home (but I still have windows, thank God!). So I cannot even be tempted to work on this thing in my free time.
