  36 // Revision 1.3  2001/06/27 23:09:16  dmitch
  37 // Pusuant to Radar 2664258, avoid all cerr-based output in NDEBUG configuration.
  38 //
  39 // Revision 1.2  2001/06/26 23:47:26  dmitch
  40 // Implemented AsnNullError as replacement for cerr in NDEBUG configuration.
  41 //
  42 // Revision 1.1.1.1  2001/05/18 23:14:06  mb
  43 // Move from private repository to open source repository
  44 //
  45 // Revision 1.3  2001/05/05 00:59:18  rmurphy
  46 // Adding darwin license headers
  47 //
  48 // Revision 1.2  2000/06/15 18:48:23  dmitch
  49 // Snacc-generated source files, now part of CVS tree to allow for cross-platform build of snaccRuntime.
  50 //
  51 // Revision 1.1.1.1  2000/03/09 01:00:05  rmurphy
  52 // Base Fortissimo Tree
  53 //
  54 // Revision 1.3  1999/04/08 21:20:18  aram
  55 // Fixed Asn1Free macro.
  56 //
  57 // Revision 1.2  1999/03/16 03:04:30  mb
  58 // Added common base class SecObject and implemented signing of the digest in SecSigner.
  59 //
  60 // Revision 1.1  1999/02/25 05:21:41  mb
  61 // Added snacc c++ library
  62 //
  63 // Revision 1.7  1995/09/07 18:48:36  rj
  64 // AsnIntType and AsnUIntType introduced to replace (unsigned) long int at a lot of places.
  65 // they shall provide 32 bit integer types on all platforms.
  66 //
  67 // Revision 1.6  1995/07/25  20:19:00  rj
  68 // changed `_' to `-' in file names.
  69 //
  70 // Revision 1.5  1995/02/13  14:47:46  rj
  71 // settings for IEEE_REAL_FMT/IEEE_REAL_LIB moved from {c_lib,c++_lib}/inc/asn_config.h to acconfig.h.
  72 //
  73 // Revision 1.4  1994/10/08  04:17:59  rj
  74 // code for meta structures added (provides information about the generated code itself).
  75 //
  76 // code for Tcl interface added (makes use of the above mentioned meta code).
  77 //
  78 // virtual inline functions (the destructor, the Clone() function, BEnc(), BDec() and Print()) moved from inc/*.h to src/*.C because g++ turns every one of them into a static non-inline function in every file where the .h file gets included.
  79 //
  80 // made Print() const (and some other, mainly comparison functions).
  81 //
  82 // several `unsigned long int' turned into `size_t'.
  83 //
  84 // Revision 1.3  1994/09/01  00:58:47  rj
  85 // redundant code moved into ../../config.h.bot; semicolon removed from end of macro texts.
  86 //
  87 // Revision 1.2  1994/08/28  10:00:47  rj
  88 // comment leader fixed.
  89 //
  90 // Revision 1.1  1994/08/28  09:20:29  rj
