Or just provide the type in the doco to guide the user. For example which is the
one to use and not get warnings from a pedantic compiler:

  unsigned long long v = rtems_configuration_get_do_zero_of_workspace();
  float v = rtems_configuration_get_do_zero_of_workspace();
  bool v = rtems_configuration_get_do_zero_of_workspace();
  int v = rtems_configuration_get_do_zero_of_workspace();
