	deprecated.
	* libcsupport/include/rtems/libcsupport.h, libcsupport/src/calloc.c,
	libcsupport/src/malloc_boundary.c,
	libcsupport/src/malloc_initialize.c,
	libcsupport/src/malloc_report_statistics_plugin.c,
	libcsupport/src/malloc_statistics_helpers.c,
	libcsupport/src/malloc_walk.c, libcsupport/src/realloc.c,
