   2  * compiler/core/mem.c - used for allocating the components of the Module
   3  *         data structure.  The program expects 0'ed memory
   4  *         to be returned by Malloc - this initializes ptrs
   5  *         to NULL.
   6  *
   7  *         If there is not enough memory the Malloc exits
   8  *         (Callers of Malloc will never get a NULL return value)

  20  * Revision 1.1  2001/06/20 21:27:57  dmitch
  21  * Adding missing snacc compiler files.
  22  *
  23  * Revision 1.1.1.1  1999/03/16 18:06:50  aram
  24  * Originals from SMIME Free Library.
  25  *
  26  * Revision 1.4  1995/07/25 19:11:50  rj
  27  * use memzero that is defined in .../snacc.h to use either memset or bzero.
  28  *
  29  * Realloc() now checks realloc(3)'s return value.
  30  *
  31  * Revision 1.3  1994/10/08  03:48:49  rj
  32  * 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.
  33  *
  34  * Revision 1.2  1994/09/01  00:39:27  rj
  35  * snacc_config.h removed; more portable .h file inclusion.
  36  *
  37  * Revision 1.1  1994/08/28  09:49:21  rj
  38  * first check-in. for a list of changes to the snacc-1.1 distribution please refer to the ChangeLog.
