(the bug you claim to be bogus was fixed already in 5.2.1..why didn't you report it earlier?!) ------------------------------------------------------------------------ [2007-09-02 20:06:52] jr-php2 at quo dot to Digging deeper, it looks like 'V' and 'N' used to work as documented until bug #38770 was "fixed in CVS". Isn't #38770 a bogus report, though? Since 'N' is documented as being unsigned, isn't the user wrong to expect it to return a negative result? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
