As Rohan points out in the comments, the Closure compiler thinks of window.myGlobal and myGlobal as different things, even though you and I know they are actually the same. If you need to define it inside a function, you could do something like

var myGlobal;
(function() { myGlobal = 42; })();
console.log(myGlobal);

or, use window in all cases:

window.myGlobal = null;
(function() { window.myGlobal = 42; })();
console.log(window.myGlobal);
