  40  * Revision 1.2  2001/05/05 00:59:27  rmurphy
  41  * Adding darwin license headers
  42  *
  43  * Revision 1.1.1.1  1999/03/16 18:06:40  aram
  44  * Originals from SMIME Free Library.

  46  * Revision 1.7  1995/09/07 19:05:01  rj
  47  * where the C++ compiler has got the bool type built-in, let the C++ backend avoid conflicts with the new keywords.
  48  *
  49  * Revision 1.6  1995/08/17  14:56:12  rj
  50  * bool added to the list of reserved words
  51  *
  52  * Revision 1.5  1995/07/25  18:22:40  rj
  53  * file name has been shortened for redundant part: c++-gen/c++-kwd -> c++-gen/kwd.
  54  *
  55  * Revision 1.4  1995/02/17  20:10:40  rj
  56  * inclusion order fixed.
  57  *
  58  * Revision 1.3  1994/10/08  03:48:04  rj
  59  * since i was still irritated by cpp standing for c++ and not the C preprocessor, i renamed them to cxx (which is one known suffix for C++ source files). since the standard #define is __cplusplus, cplusplus would have been the more obvious choice, but it is a little too long.
  60  *
  61  * Revision 1.2  1994/09/01  00:19:44  rj
  62  * snacc_config.h removed; more portable .h file inclusion.
  63  *
  64  * Revision 1.1  1994/08/28  09:48:11  rj
  65  * first check-in. for a list of changes to the snacc-1.1 distribution please refer to the ChangeLog.
