Subject: [PATCH v2 2/6] msvc: opendir: allocate enough memory

From: Erik Faye-Lund <[email-masked]>
Date: Tue, 23 Nov 2010 19:38:25 +0100

The defintion of DIR expects the allocating function to extend
dd_name by over-allocating. This is not currently done in our
implementation of opendir. Fix this.
