Simplify with assumptions

Using Mathematic 4.1, Why won't the 2nd expression simplify?

Simplify[1 - c^2,  s^2 + c^2 == 1]

Simplify[1 - s^2,  s^2 + c^2 == 1]
1 - s^2

Why doesn't this 2nd expression yield c^2?

The leaf count of both s^2 and c^2 are 3.
While the leaf count for both 1 - s^2 and 1 - c^2 are 7.
