/*			- lowinit.c -

  The function __low_level_init is called by the start-up code before doing
  the normal initialization of data segments. If the return value is zero,
  initialization is not performed.

  In the run-time library there is a dummy __low_level_init, which does
  nothing but return 1. This means that the start-up routine proceeds with
  initialization of data segments.

  To replace this dummy, compile a customized version (like the example
  below) and link it with the rest of your code.
