/** RCS log of revisions to the C source code.
 *
 * \begin{verbatim}
 * $Log: stdio.c,v $
 * Revision 1.7  2007/04/24 01:43:29  swift
 * Added acknowledgement and funding attribution.
 *
 * Revision 1.6  2006/12/26 20:58:38  swift
 * Fixed an error in a comment.
 *
 * Revision 1.5  2006/10/13 18:55:29  swift
 * Added fstreamok() validation to most functions that use FILE objects.
 * Modified fstreamcrc() to speed up the calculation and cut overhead.
 *
 * Revision 1.4  2006/10/11 21:05:43  swift
 * Implemented the new flashio file system.
 *
 * Revision 1.3  2006/04/21 13:45:40  swift
 * Changed copyright attribute.
 *
 * Revision 1.2  2004/12/29 23:06:50  swift
 * Modified LogEntry() to use strings stored in the CODE segment.  This saves
 * lots of space in the DATA segment and significantly speeds code start-up.
 *
 * Revision 1.1  2004/07/14 22:52:56  swift
 * A new implmentation of the stdio library.
 *
 * Revision 1.3  2003/11/20 18:59:35  swift
 * Added GNU Lesser General Public License to source file.
 *
 * Revision 1.2  2003/06/07 20:44:15  swift
 * Fixed a bug in fprintf() - the output was always written to stdout
 * regardless of what the stream pointer in the function argument was.
 * Also implemented printf() by calling vfprintf() with stdout as the
 * stream pointer.
 *
 * Revision 1.1  2003/05/31 22:11:25  swift
 * Initial revision
