8 * Updated WIN32 code specific sections. Changed header.
10 * Revision 1.19 1998/11/03 10:16:11 adam
11 * Uses stat and not lstat so that file traversal follows symbolic links.
13 * Revision 1.18 1997/09/25 14:55:33 adam
14 * Windows port uses stat and not lstat.
16 * Revision 1.17 1997/09/09 13:38:06 adam
17 * Partial port to WIN95/NT.
19 * Revision 1.16 1996/10/29 14:06:45 adam

22 * Revision 1.15 1996/06/04 10:18:58 adam
23 * Minor changes - removed include of ctype.h.
25 * Revision 1.14 1996/04/09 06:49:18 adam
26 * Traversal of directories doesn't follow symbolic links.
28 * Revision 1.13 1996/03/21 14:50:08 adam
29 * File update uses modify-time instead of change-time.
31 * Revision 1.12 1996/02/05 12:29:55 adam
32 * Logging reduced a bit.
33 * The remaining running time is estimated during register merge.
35 * Revision 1.11 1995/11/20 16:59:44 adam
36 * New update method: the 'old' keys are saved for each records.
38 * Revision 1.10 1995/11/20 11:56:22 adam
39 * Work on new traversal.
41 * Revision 1.9 1995/10/30 13:42:12 adam
