The pragma No_Run_Time is used to achieve an affect similar
to the use of the "Zero Foot Print" configurable run time, but without
requiring a specially configured run time. The result of using this
pragma, which must be used for all units in a partition, is to restrict
the use of any language features requiring run-time support code. The
preferred usage is to use an appropriately configured run-time that
includes just those features that are to be made accessible.
