	18446744073709551615 to unsigned bigint column
	this not happens with hex value (0xffffffffffffffff)
>How-To-Repeat:
#
# Table structure for table 'ad'
#
CREATE TABLE ad (
  id bigint(20) unsigned DEFAULT '0' NOT NULL auto_increment,
  client bigint(20) DEFAULT '0' NOT NULL,
  target bigint(20) unsigned DEFAULT '0' NOT NULL,
  category bigint(20) unsigned DEFAULT '0' NOT NULL,
  image varchar(255) DEFAULT 'UNKNOWN' NOT NULL,
  reference varchar(255) DEFAULT 'UNKNOWN' NOT NULL,
  impressions int(10) unsigned DEFAULT '0' NOT NULL,
  clicks bigint(20) unsigned DEFAULT '0' NOT NULL,
  status enum('on','off','pending') DEFAULT 'pending' NOT NULL,
  PRIMARY KEY (id)
);

#
# Dumping data for table 'ad'
#

INSERT INTO ad VALUES (1,1,18446744073709551615,1,'http://pekod.trans-m-radio.com/banners/bannerd10652.gif','http://www.one.com',30,0,'on');
INSERT INTO ad VALUES (2,2,18446744073709551615,1,'http://pekod.trans-m-radio.com/banners/bannero10648.gif','http://www.two.com',94,0,'on');

This program have the same effect: (tested under FreeBSD 3.0 and RedHat 5.1)

#include <stdio.h>
void main (void) {
unsigned long long ull=18446744073709551615ULL;
double d;
d = (double) ull;
printf("double   value %f\n", d);
printf("longlong value %qu\n", ull);
ull = (unsigned long long) d;
}

>Fix:
	???
	It happpens on line 1361 of sql/field.cc
