It does. The warning is intended to make developers aware that AS
doesn't has function-scoped, not block-scoped. variables. When you
declare a var anywhere inside a function, it's scope is the entire
function, not just the { ... } block it's in. So multiple declarations
are redundant; they don't declare separate vars with their own initial
values. For example, if you write this code inside a function
if (condition)
{
var i:int;
...
i = 3;
...
}
else
{
var i:int;
trace(i);
}
it should trace out 3, not 0. You may not like this feature of AS (I
don't) but it's required for ECMAScript compatibility.

You can change them for mxmlc in it's config XML. Maybe FB will take
note if
you change things there too ?
