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);
}
