+ * fixinc/server.c (load_data, run_shell): Use xmalloc, xrealloc &
+ xcalloc in lieu of malloc, realloc & calloc.
+
+ * gencheck.c (xmalloc): Use really_call_malloc, not malloc.
+
+ * gengenrtl.c (xmalloc): Likewise.
+
+ * gensupport.c (xcalloc, xrealloc, xmalloc): Use the
+ really_call_* memory allocation routines.
+
+ * stmt.c (check_for_full_enumeration_handling): Use
+ really_call_calloc, not calloc.
+
+ * system.h (really_call_malloc, really_call_calloc,
+ really_call_realloc): Define.
+ (malloc, realloc, calloc, strdup, bzero, bcmp, rindex): Poison.
