Bug description:  strtotime, strftime, weekday & monday & year leap

Description:
------------
This code fails on two weeks. Week 1, year printed is 2009 instead of dec
29 2008 and week 52, year printed is 2009 instead of Jan 3 2010.

Bug or feature or am I doing something wrong ?
 

Reproduce code:
---------------
setlocale(LC_ALL, "fr_FR.utf8");
date_default_timezone_set("Europe/Paris");

// Get the number of weeks in a year
$weeks = date("W", mktime(0,0,0,12,31, 2009));
// print the 1st monday of each week with year
for($i=1; $i <= $weeks; $i++)
{
	if(strlen($i) == 1) $w = "0" . $i; else $w = $i;
	echo strftime("%A %e %B %G", strtotime("2009W$w")) . " - " .strftime("%A
%e %B %G", strtotime("2009W$w +6days"));
}



Expected result:
----------------
lundi 28 d�cembre 2008 instead of lundi 28 d�cembre 2009

dimanche 3 janvier 2010 instead of dimanche 3 janvier 2009


Actual result:
--------------
Actual code output. Submitted code stripped to revelant part only.
