        var s = window[func];
        window[func] = function (a) {

As another poster mentioned, the problem is that your variable s is getting overwritten each time through the loop. Instead, try

function overwrite(f){
    return function(a){
        var ret=f(a);
        console.log(f);
        return ret;
    };
}

for (func in window) {
    if (typeof window[func] === 'function' && typeof window[func] != 'undefined') {
        window[func]=overwrite(window[func]);
    }
}

alert("hehe");
