<p><b>Addresses: filesys.ts</b></p>
<p>The specification can be read to require the existence test. As this introduces a
race, the existence test must not happen.</p>
<p>Change to: "Effects: <code>p</code> is removed as if by POSIX <code>remove()</code>."</p>

<p><i>[2014-02-13 LWG/SG-3 Issaquah: Insufficient consensus for change. Vote for NAD: 9 0 0 2 1.]</i></p>
  
  


<p id="res-2630"><b>Proposed resolution:</b></p>
<p>This wording is relative to <a href="http://wiki.edg.com/twiki/pub/Wg21issaquah/SG3/working-draft.html">SG3 working draft</a>.</p>

<ol><li><p>Change 15.28 [filesys.ts::fs.op.remove] as indicated:</p>

<blockquote><p>
<i>Effects</i>: <del>If <code>exists(symlink_status(p,ec))</code>, it</del><ins><code>p</code></ins> is removed as if by POSIX <code>remove()</code>.
