	* sem_aggr.adb
	(Resolve_Array_Aggregate): refine the check for a static expression, to
	recognize also static ranges
	* sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
	Array_Type_Declaration): postpone the test for the type being a subtype
	mark after the type has been resolved, so that component-selection and
	expanded-name are discriminated.
	(Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
	to distinguish the case of an iteration scheme, so that an error is
	issed on a non-static range in SPARK except in an iteration scheme.
	* sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
	In_Iter_Schm = True.
	* sem_ch6.adb (Analyze_Subprogram_Specification): refine the check for
	user-defined operators so that they are allowed in renaming
	* sem_ch8.adb
	(Find_Selected_Component): refine the check for prefixing of operators
	so that they are allowed in renaming. Move the checks for restrictions
	on selector name after analysis discriminated between
	component-selection and expanded-name.
	* sem_res.adb (Resolve_Op_Concat_Arg): do not issue a warning on
	concatenation argument of string type if it is static.
	* sem_util.adb, sem_util.ads
	(Check_Later_Vs_Basic_Declarations): add a new function
	Is_Later_Declarative_Item to decice which declarations are allowed as
	later items, in the two different modes Ada 83 and SPARK. In the SPARK
	mode, add that renamings are considered as later items.
	(Enclosing_Package): new function to return the enclosing package
	(Enter_Name): correct the rule for homonyms in SPARK
	(Is_SPARK_Initialization_Expr): default to returning True on nodes not
	from source (result of expansion) to avoid issuing wrong warnings.

	* opt.ads (SPARK_Mode): update comment, SPARK_Mode only set through
	command line now.
	* par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
	expression is a simple expression. This check cannot be performed in
	the semantics, so just drop it.
	(P_Index_Or_Discriminant_Constraint): move check that the index or
	discriminant is a subtype mark to Analyze_Subtype_Declaration in the
	semantics. Other cases were previously checked in the semantics.
	* par-ch4.adb (P_Name): move checks that a selector name is not
	character literal or an operator symbol to Find_Selected_Component in
	the semantics
	* par-ch5.adb (Parse_Decls_Begin_End): move check that basic
	declarations are not placed after later declarations in a separate
	procedure in Sem_Util (possibly not the best choice?), to be used both
	during parsing, for Ada 83 mode, and during semantic analysis, for
	SPARK mode.
	* par-endh.adb (Check_End): move check that end label is not missing
	to Process_End_Label in the semantics
	* par-prag.adb (Process_Restrictions_Or_Restriction_Warnings): remove
	the special case for SPARK restriction

	* restrict.adb, restrict.ads (Check_Formal_Restriction): add a
	parameter Force to issue the error message even on internal node (used
	for generated end label). Call Check_Restriction to check when an error
	must be issued. In SPARK mode, issue an error message even if the
	restriction is not set.
	(Check_Restriction): new procedure with an additional out parameter to
	inform the caller that a message has been issued
	* sem_aggr.adb: Minor modification of message
	* sem_attr.adb (Analyze_Attribute): call Check_Formal_Restriction
	instead of issuing an error message directly
	* sem_ch3.adb (Analyze_Declarations): move here the check that basic
	declarations are not placed after later declarations, by calling
	Check_Later_Vs_Basic_Declarations
	(Analyze_Subtype_Declaration): move here the check that an index or
	discriminant constraint must be a subtype mark. Change the check that
	a subtype of String must start at one so that it works on subtype marks.
	* sem_ch4.adb (Analyze_Call): move here the check that a named
	association cannot follow a positional one in a call
	* sem_ch5.adb (Check_Unreachable_Code): call Check_Formal_Restriction
	instead of issuing an error message directly
	* sem_ch8.adb (Find_Selected_Component): move here the check that a
	selector name is not a character literal or an operator symbol. Move
	here the check that the prefix of an expanded name cannot be a
	subprogram or a loop statement.
	* sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
	procedure called from parsing and semantics to check that basic
	declarations are not placed after later declarations
	(Process_End_Label): move here the check that end label is not missing
