 * Revision 1000.0  2003/10/29 16:33:02  gouriano
 * PRODUCTION: IMPORTED [ORIGINAL] Dev-tree R6.9
 *
 * Revision 6.9  2003/08/28 19:28:47  ucko
 * Use macros for kXxxTimeout on all platforms (safer, inasmuch as the C
 * include directory may be first).
 *
 * Revision 6.8  2003/08/28 18:47:25  ucko
 * Go back to previous WorkShop hack, but include connect_export.h (for
 * ncbiconf.h) so that it actually works reliably this time around.
 *
 * Revision 6.7  2003/08/27 12:32:25  ucko
 * Yet another attempt to work around the WorkShop lossage with k*Timeout.
 *
 * Revision 6.6  2003/08/27 02:00:11  ucko
 * Sigh... WorkShop still mishandles kXxxTimeout in some cases, so fall
 * back to making them macros.
 *
 * Revision 6.5  2003/08/26 18:55:13  lavr
 * Added "static" to k...Timeout to make Sun WorkShop compiler happier
 *
 * Revision 6.4  2003/08/25 14:36:26  lavr
 * +kDefaultTimeout, +kInfiniteTimeout
 *
 * Revision 6.3  2003/04/09 19:05:58  siyan
 * Added doxygen support
 *
 * Revision 6.2  2002/09/19 18:05:41  lavr
 * Header file guard macro changed; log moved to end
 *
 * Revision 6.1  2001/06/19 20:15:58  lavr
 * Initial revision
