	* prj-env.adb: Minor code reorganization.
	* par-ch3.adb: Minor reformatting.
	* gcc-interface/Make-lang.in: Update dependencies.

2010-09-09  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch9.adb (Build_Activation_Chain_Entity): The construct enclosing
	a task declaration can be an entry body.

	* exp_disp.adb (Make_DT): Decorate as "static" variables containing
	tags of library level tagged types.
	(Make_Tags): Disable backend optimizations about aliasing for
	declarations of access to dispatch tables.

	* sem_ch12.adb (Reset_Entity): If the entity is an itype created as a
	subtype for a null-excluding access type, recover the original
	subtype_mark to get the proper visibility on the original name.

	* exp_ch3.adb (Build_Untagged_Equality): For Ada2012, new procedure to
	create the primitive equality operation for an untagged record. The
	operation is the predefined equality if no record component has a
	user-defined equality, or if there is a user-defined equality for the
	type as a whole, or when the type is derived and it has an inherited
	equality. Otherwise the body of the operations is built as for tagged
	types.
	(Expand_Freeze_Record_Type): Call Build_Untagged_Equality when needed.
	(Make_Eq_Body): New function to create the expanded body of the equality
	operation for tagged and untagged records.  In both cases the operation
	composes, and the primitive operation of each record component is used
	to generate the equality function for the type.
	* exp_ch4.adb (Expand_Composite_Equality): In Ada2012, if a component
	has an abstract equality defined, replace its call with a
	Raise_Program_Error.
	* sem_ch6.adb (New_Overloaded_Entity): if Ada2012, verify that a
	user-defined equality operator for an untagged record type does not
	happen after type is frozen, and appears in the visible part if partial
	view of type is not limited.

	* gnatlbr.adb: Make Create_Directory more portable: use __gnat_mkdir.

2010-09-09  Bob Duff  <duff@adacore.com>

	* gnat_ugn.texi: Remove incorrect statement about -E being the default.
