2011-08-03  Yannick Moy  <moy@adacore.com>

	* sem_ch6.adb (New_Overloaded_Entity): only issue error for SPARK
	restriction on overloaded entity if the entity is not an operator.

2011-08-03  Yannick Moy  <moy@adacore.com>

	* sem_ch7.adb, sem_res.adb, sem_attr.adb, restrict.adb,
	restrict.ads: Rename remaining Check_Formal_Restriction* into
	Check_SPARK_Restriction*.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

	* prj-proc.adb, prj-part.adb, prj.adb, prj.ads, prj-nmsc.adb,
	prj-nmsc.ads, prj-err.adb (Project_Data): now discriminated on its
	qualifier.
	(Project_Empty): removed
	(Empty_Project): new parameter Qualifier
	This is used to have fields specific to aggregate projects, cleaner
	New field to store the list of aggregated projects.
	(Check_Aggregate_Project): removed
	(Process_Aggregated_Projects, Free): new subprograms.
