 *  ======== lock.c ========
 *  TIRTOS provides an implementation for the sys/lock APIs if re-entrancy
 *  support is enabled. If re-entrancy support is disabled or an app is built
 *  without TIRTOS but using the libraries built for TIRTOS, these empty
 *  stubs are required to succesfully link the app.
