//    3   The function __low_level_init is called by the start-up code before doing
//    4   the normal initialization of data segments. If the return value is zero,
//    5   initialization is not performed.
//    6 
//    7   In the run-time library there is a dummy __low_level_init, which does
//    8   nothing but return 1. This means that the start-up routine proceeds with
//    9   initialization of data segments.
//   10 
//   11   To replace this dummy, compile a customized version (like the example
//   12   below) and link it with the rest of your code.
