Bug: Contrib\fulltextindex\fti.c? - Mailing list pgsql-bugs

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);
}
