 Priority:  normal               |  Milestone:  4.12
Component:  RTEMS Configuration  |    Version:  4.12
 Severity:  normal               |   Keywords:
---------------------------------+-----------------------------
 In 4.11, the minimum executable did not include open() and close() because
 the methods rtems_libio_post_driver() and rtems_libio_exit() were not
 included in the executable. On the master, these two methods are showing
 up in minimum and pulling in these methods.

 The dependency chain used to be if the console driver was installed, we
 needed to open and close stdin, stdout, and stderr. Now even without the
 console configured these are included.

 FWIW the minimum size looks pretty good on the master for sis. Fixing this
 would likely drop it at least another 5%.
