exp_strm.adb (Build_Stream_Attr_Profile, [...]): Add the null-excluding attribute to the first formal.

2005-11-14  Javier Miranda  <miranda@adacore.com>

	* exp_strm.adb (Build_Stream_Attr_Profile, Build_Stream_Function,
	Build_Stream_Procedure): Add the null-excluding attribute to the first
	formal.
	This has no semantic meaning under Ada95 mode but it is a
	requirement under Ada05 mode.

	* par-ch3.adb (P_Access_Definition): Addition of warning message if
	the null exclusion is used under Ada95 mode
	(P_Null_Exclusion): The qualifier has no semantic meaning in Ada 95.
	(P_Access_Definition): Remove assertion that forbids the use of
	the null-exclusion feature in Ada95.
