/* Note Newlib support has been included by popular demand, but is not
 * used by the FreeRTOS maintainers themselves.  FreeRTOS is not
 * responsible for resulting newlib operation.  User must be familiar with
 * newlib and must provide system-wide implementations of the necessary
 * stubs. Be warned that (at the time of writing) the current newlib design
 * implements a system-wide malloc() that must be provided with locks.
 *
 * See the third party link http://www.nadler.com/embedded/newlibAndFreeRTOS.html
