* 3vtrasym.adb, 5vtraent.ads, sprint.adb,

	sem_ch10.adb: Minor reformatting

	* exp_ch5.adb (Expand_Assign_Array): Test for bit unaligned operands
	(Expand_Assign_Record): Test right hand side for bit unaligned as well

	* 3vtrasym.adb:
	* 5vtraent.adb:
	* 5vtraent.ads:
	* tb-alvms.c:
	Support for TBK$SYMBOLIZE-based symbolic traceback.

	* exp_disp.adb:
	Revert previous change, that did not work well when pragma No_Run_Time
	was used in conjunction with a run-time other than ZFP.

	* make.adb:
	(Gnatmake): When there are no Ada mains in attribute Main, disable the
	 bind and link steps only is switch -z is not used.

	* Makefile.generic: Remove duplicated setting of CC.

	* Makefile.prolog: Set CC to gcc by default, to override make's
	default (cc).

	* einfo.h: Regenerated.

	* sem_ch10.adb (Analyze_Subunit): Restore state of suppress flags for
	current body, after compiling subunit.

	* itypes.adb (Create_Itype): In ASIS_Mode, do not freeze the itype
	when in deleted code, because gigi needs properly ordered freeze
	actions to annotate types.

	* freeze.adb (Is_Fully_Defined): Predicate must be recursive, to
	prevent the premature freezing of record type that contains
	subcomponents with a private type that does not yet have a completion.

	* sem_ch12.adb:
	(Analyze_Package_Instantiation): Check that instances can not be used in
	limited with_clauses.

	* sem_ch8.adb:
	(Analyze_Package_Renaming): Check that limited withed packages cannot
	be renamed. Improve text on error messages related to limited
	with_clauses.

	* einfo.adb, einfo.ads: Remove Non_Limited_Views attribute.

	* sprint.adb: (Sprint_Node_Actual): Print limited with_clauses.
	Update copyright notice.

	* sem_ch10.adb: (Build_Limited_Views): Complete its documentation.
	(Install_Limited_Context_Clauses): New subprogram that isolates all the
	checks required for limited context_clauses and installs the limited
	view.
	(Install_Limited_Withed_Unit): Complete its documentation.
	(Analyze_Context): Check that limited with_clauses are only allowed in
	package specs.
	(Install_Context): Call Install_Limited_Context_Clauses after the
	parents have been installed.
	(Install_Limited_Withed_Unit): Add documentation. Mark the installed
	package as 'From_With_Type'; this mark indicates that the limited view
	is installed. Used to check bad usages of limited with_clauses.
	(Build_Limited_Views): Do not add shadow entities to the scope's list
	of entities. Do not add real entities to the Non_Limited_Views chain.
	Improve error notification.
	(Remove_Context_Clauses): Remove context clauses in two phases:
	limited views first and regular views later (to maintain the
	stack model).
	(Remove_Limited_With_Clause): If the package is analyzed then reinstall
	its visible entities.

	* sem_type.adb (Specific_Type): Type Universal_Fixed is compatible
	with any type that Is_Fixed_Point_Type.

	* sinfo.ads: Fix documentation for Associated_Node attribute.

	* switch-c.adb (Scan_Front_End_Switches): ASIS_Mode is set now when
	both '-gnatc' and '-gnatt' are specified.

	* atree.adb (Initialize): Add initialization for Node_Count (set to
	zero).

	* decl.c (gnat_to_gnu_entity, case E_Subprogram): If no return value,
	do not consider as Pure.

	Part of implementation of function-at-a-time:

	* trans.c (gnat_to_gnu_code): If IS_STMT, call expand_expr_stmt.
	(tree_transform): Add new argument to build_component_ref.
	(tree_transform, case N_Assignment_Statement): Make and return an
	EXPR_STMT.
	(tree_transform): If result IS_STMT, set flags and return it.
	(gnat_expand_stmt, set_lineno_from_sloc): New functions.

	* utils2.c (build_simple_component_ref, build_component_ref): Add new
	arg, NO_FOLD_P.
	(build_binary_op, case EQ_EXPR): Pass additional arg to it.
	(build_allocator): Likewise.

	* utils.c (convert_to_fat_pointer, convert_to_thin_pointer, convert):
	Add new arg to build_component_ref.
	(maybe_unconstrained_array, unchecked_convert): Likewise.

	* ada-tree.def (EXPR_STMT): New code.

	* ada-tree.h (IS_STMT, TREE_SLOC, EXPR_STMT_EXPR): New macros.

	* decl.c (gnat_to_gnu_entity, case object): Add extra arg to
	build_component_ref calls.

	* misc.c (gnat_expand_expr): If IS_STMT, call gnat_expand_stmt.

	* gigi.h (gnat_expand_stmt, set_lineno_from_sloc): New functions.
	(build_component_ref): Add new argument, NO_FOLD_P.
