CONFIGURE_MEMORY_OVERHEAD
-------------------------
CONSTANT:
``CONFIGURE_MEMORY_OVERHEAD``
DATA TYPE:
Unsigned integer (``size_t``).
RANGE:
Zero or positive.
DEFAULT VALUE:
The default value is 0.
DESCRIPTION:
This parameter is set to the number of kilobytes the application wishes to
add to the requirements calculated by ``<rtems/confdefs.h>``.
NOTES:
This configuration parameter should only be used when it is suspected that
a bug in ``<rtems/confdefs.h>`` has resulted in an underestimation.
Typically the memory allocation will be too low when an application does
not account for all message queue buffers or task stacks.

Seldom Used Configuration Parameters
====================================
This section describes configuration parameters supported by
``<rtems/confdefs.h>`` which are seldom used by applications. These parameters
tend to be oriented to debugging system configurations and providing
work-arounds when the memory estimated by ``<rtems/confdefs.h>`` is incorrect.
