/* Previous revision history from mach386/attache.h
 * with release update messages removed
 *
 * Revision 2.4  1994/12/20  21:19:11  lowell
 * worked around problems between Mach's memory.h and
 * the builtin versions provided by GCC...
 *
 * Revision 2.3  1994/09/04  23:55:50  sra
 * Get rid of most of the ancient NO_PP cruft.
 *
 * Revision 2.2  1994/09/04  06:13:38  sra
 * Clean up antique type names and install macros.
 *
 * Revision 1.6  1993/08/03  23:40:54  dab
 * CONFIG_PREAMBLE is either defined or not, so use #ifdef
 *
 * Revision 1.5  1993/08/02  21:58:54  dab
 * moved MEM* and STR* to the first section
 *
 * Revision 1.4  1993/04/21  15:30:10  dab
 * Default configuration moved to <attache/h/config.h>
 *
 * Revision 1.2  1993/02/28  17:25:09  dab
 * If set SGRP to 1 instead of just on then matches what happens in
 * envoy/h/asn1conf.h.
