Bug: Contrib\fulltextindex\fti.c?

Hello,

Is it me, or does the declaration of difference as an unsigned int
prevent the if statements just below from working correctly?
Should it not be a normal int?

>From postgresql-7.0.2/contrib/fulltextindex/fti.c
======
bool
is_stopword(char *text)
{
	char	  **StopLow;		/* for list of stop-words */
	char	  **StopHigh;
	char	  **StopMiddle;
	unsigned int difference;

	StopLow = &StopWords[0];	/* initialize stuff for binary search */
	StopHigh = endof(StopWords);

	if (lengthof(StopWords) == 0)
		return false;

	while (StopLow <= StopHigh)
	{
		StopMiddle = StopLow + (StopHigh - StopLow) / 2;
		difference = strcmp(*StopMiddle, text);
		if (difference == 0)
			return (true);
		else if (difference < 0)
			StopLow = StopMiddle + 1;
		else
			StopHigh = StopMiddle - 1;
	}

	return (false);
}
