There are two cases: -- -- If Configuration_Pragmas is False, Par parses a compilation unit in the -- current source file and sets the Cunit, Cunit_Entity and Unit_Name fields -- of the units table entry for Current_Source_Unit. On return the parse tree -- is complete, and decorated with any required implicit label declarations. -- The value returned in this case is always No_List. -- -- If Configuration_Pragmas is True, Par parses a list of configuration -- pragmas from the current source file, and returns the list of pragmas.
