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

* Revision 1.4 1995/07/25 19:11:50 rj
* use memzero that is defined in .../snacc.h to use either memset or bzero.
*
* Realloc() now checks realloc(3)'s return value.
*
* Revision 1.3 1994/10/08 03:48:49 rj
* 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.
*
* Revision 1.2 1994/09/01 00:39:27 rj
* snacc_config.h removed; more portable .h file inclusion.
*
* Revision 1.1 1994/08/28 09:49:21 rj
* first check-in. for a list of changes to the snacc-1.1 distribution please refer to the ChangeLog.
