	* gnatlink.adb (Process_Args): Call Executable_Name on argument of -o
	with Only_If_No_Suffix set to True.
	* osint.adb (Executable_Name): Do not add executable suffix if there is
	already a suffix and Only_If_No_Suffix is True.
	* osint.ads (Executable_Name): New Boolean parameter Only_If_No_Suffix,
	defaulted to False.

	* exp_atag.adb (Build_TSD): Change argument name because the actual is
	now the address of a tag (instead of the tag). Update implementation
	accordingly.
	(Build_CW_Membership): New implementation. Converted into a procedure
	because it has an additional out mode parameter. Its implementation has
	been rewritten to improve the generated code but also to facilitate
	referencing the relocated object node in the caller.
	* exp_atag.ads (Build_CW_Membership): Update profile and documentation.
	* sinfo.ads (N_SCIL_Membership_Test) New_Node.
	(SCIL_Tag_Value): New field of N_SCIL_Membership_Test nodes.
	(Is_Syntactic_Field): Add entry of new node.
	(SCIL_Tag_Value/Set_SCIL_Tag_Value): New subprograms.
	* sinfo.adb (SCIL_Related_Node, SCIL_Entity): Update assertions to
	handle N_SCIL_Membership_Test nodes.
	(SCIL_Tag_Value/Set_SCIL_Tag_Value): New subprograms.
	* sem.adb (Analyze): Add null management for new node.
	* sem_scil.adb (Find_SCIL_Node): Add null management for new node.
	(Check_SCIL_Node): Add checks of N_SCIL_Membership_Test nodes.
	* exp_ch4.adb (Tagged_Membership): Change profile from function to
	procedure. Add generation of SCIL node associated with class-wide
	membership test.
	(Expand_N_In): Complete decoration of SCIL nodes.
	* exp_intr.adb (Expand_Dispatching_Constructor_Call): Tune call to
	Build_CW_Membership because its profile has been changed.
	* exp_util.adb (Insert_Actions): Add null management for new node.
	* sprint.adb (Sprint_Node_Actual): Handle new node.
	* gcc-interface/trans.c Add no processing for N_SCIL_Membership_Test
	nodes.
	* gcc-interface/Make-lang.in: Update dependencies.

	* opt.ads: New flags Init_Or_Norm_Scalars_Config,
	Initialize_Scalars_Config, to capture the presence of the corresponding
	pragmas in a configuration file.
	* opt.adb (Register_, Save_, Set_, Restore_Opt_Configuration_Switches):
	handle new flags so that they are restored for each compilation unit.
	* frontend.adb: At the end of compilation, scan the context of the main
	unit to recover occurrences of pragma Initialize_Scalars, to annotate
	the ALI file accordingly.
