This one handles February 29 - treating March 1st as the celebration day in non-leap years.

SELECT u.name
FROM users u INNER JOIN friendships f ON (f.user_id = u.id)
WHERE f.friend_id = 6 -- whatever your id is
    AND (
        MONTH(u.birthdate) = MONTH(NOW())
        AND DAY(u.birthdate) = DAY(NOW())
    ) OR (
        MONTH(c.birthdate) = 2 AND DAY(c.birthdate) = 29
        AND MONTH(NOW()) = 3 AND DAY(NOW()) = 1
        AND (YEAR(NOW()) % 4 = 0)
        AND ((YEAR(NOW()) % 100 != 0) OR (YEAR(NOW()) % 400 = 0))
    )

Having not see your table structure, I just made a guess about how you handle friendship links
