How to fill 100% of remaining width

Is there any work around to do something like this work as expected? I wish there were something like that width:remainder; or width:100% - 32px;.

width: auto; doesn't works.

I think the only way possible is working around with paddings/margins, negative values, or float, or some html tags hack. I tried also display:block;.

I like to get the same result as this, without tables http://jsfiddle.net/LJGWY/

<div style="position: absolute; width: 100%; height: 100px; border: 3 solid red;" id="container">
    <div style="display:inline; width: (100%-100px); border: 3 solid green;">Fill</div>
    <div style="display:inline; width: 100px; border: 3 solid blue;">Fixed</div>
</div>
