	* sem_res.adb (Resolve_Selected_Component): do not generate a
	discriminant check if the selected component is a component of
	the argument of an initialization procedure.

	* trans.c (tree_transform, case of arithmetic operators): If result
	type is private, the gnu_type is the base type of the full view,
	given that the full view itself may be a subtype.

	* sem_res.adb: Minor reformatting

	* trans.c (tree_transform, case N_Real_Literal): Add missing third
	parameter in call to Machine (unknown horrible effects from this
	omission).

	* urealp.h: Add definition of Round_Even for call to Machine
	Add third parameter for Machine

	* sem_warn.adb (Check_One_Unit): Suppress warnings completely on
	predefined units in No_Run_Time mode.

	* misc.c (insn-codes.h): Now include.

	* a-except.adb: Preparation work for future integration of the GCC 3
	exception handling mechanism
	(Notify_Handled_Exception, Notify_Unhandled_Exception): New routines
	to factorize previous code sequences and make them externally callable,
	e.g. for the Ada personality routine when the GCC 3 mechanism is used.
	(Propagate_Exception, Raise_Current_Excep, Raise_From_Signal_Handler):
	Use the new notification routines.

	* prj-tree.ads (First_Choice_Of): Document the when others case

	* bindgen.adb (Gen_Ada_Init_*): Set priority of environment task in
	HI-E mode, in order to support Ravenscar profile properly.

	* cstand.adb (Create_Standard): Duration is a 32 bit type in HI-E
	mode on 32 bits targets.

	* fmap.adb: Initial version.

	* fmap.ads: Initial version.

	* fname-uf.adb (Get_File_Name): Use mapping if unit name mapped.
	If search is successfully done, add to mapping.

	* frontend.adb: Initialize the mapping if a -gnatem switch was used.

	* make.adb:
	(Gnatmake): Add new local variable Mapping_File_Name.
	 Create mapping file when using project file(s).
	 Delete mapping file before exiting.

	* opt.ads (Mapping_File_Name): New variable

	* osint.adb (Find_File): Use path name found in mapping, if any.

	* prj-env.adb (Create_Mapping_File): New procedure

	* prj-env.ads (Create_Mapping_File): New procedure.

	* switch.adb (Scan_Front_End_Switches): Add processing for -gnatem
	(Mapping_File)

	* usage.adb: Add entry for new switch -gnatem.

	* Makefile.in: Add dependencies for fmap.o.

	* sem_ch10.adb (Analyze_With_Clause): Retrieve proper entity when unit
	is a package instantiation rewritten as a package body.
	(Install_Withed_Unit): Undo previous change, now redundant.

	* layout.adb:
	(Compute_Length): Move conversion to Unsigned to callers.
	(Get_Max_Size): Convert Len expression to Unsigned after calls to
	Compute_Length and Determine_Range.
	(Layout_Array_Type): Convert Len expression to Unsigned after calls to
	Compute_Length and Determine_Range.
	Above changes fix problem with length computation for supernull arrays
	where Max (Len, 0) wasn't getting applied due to the Unsigned
	conversion used by Compute_Length.

	* rtsfind.ads:
	(OK_To_Use_In_No_Run_Time_Mode): Allow Ada.Exceptions and
	 System.Secondary_Stack.
	(OK_To_Use_In_Ravenscar_Mode): New table needed to implement Ravenscar
	 in HI-E mode.
	Remove unused entity RE_Exception_Data.

	* rtsfind.adb (RTE): Allow Ravenscar Profile in HI mode.

	* rident.ads (No_Secondary_Stack): New restriction.
