	* exp_ch4.adb (Expand_N_Op_Eq): When looking for the primitive equality
	for a tagged type, verify that both formals have the same type.

	* exp_ch6.adb (Add_Call_By_Copy_Code): Initialize properly the
	temporary when the formal is an in-parameter and the actual a possibly
	unaligned slice.

	* exp_ch9.adb (Expand_Entry_Barrier): Resolve barrier expression even
	when expansion is disabled, to ensure proper name capture with
	overloaded literals.  Condition can be of any boolean type, resolve
	accordingly.

	* sem_ch8.adb (Analyze_Subprogram_Renaming): Emit warning if the
	renaming is for a formal subprogram with a default operator name, and
	there is a usable operator that is visible at the point of
	instantiation.

2004-02-09  Robert Dewar  <dewar@gnat.com>

	* ali.adb (Scan_Ali) Add Ignore_Errors argument. This is a major
	rewrite to ignore errors in ali files, intended to allow tools downward
	compatibility with new versions of ali files.

	* ali.ads: Add new parameter Ignore_Errors

	* bcheck.adb (Check_Consistent_Restrictions): Fix error of sometimes
	duplicating the error message giving the file with restrictions.

	* debug.adb: Add debug flag I for gnatbind

	* errout.adb (Set_Msg_Insertion_Node): Suppress extra quotes around
	operators for the case where the operator is a defining operator.

	* exp_ch3.adb: Minor reformatting (new function spec format).

	* exp_ch4.adb: Add comment for previous change, and make minor
	adjustment to loop to always check for improper loop termination.
	Minor reformatting throughout (new function spec format).

	* gnatbind.adb: Implement -di debug flag for gnatbind

	* gnatlink.adb: Call Scan_ALI with Ignore_Errors set to True

	* gnatls.adb: Call Scan_ALI with Ignore_Errors set to True

	* lib-load.adb: Fix bad assertion.
	Found by testing and code reading.
	Minor reformatting.

	* lib-load.ads: Minor reformatting.

	* lib-writ.adb: There is only one R line now.

	* lib-writ.ads: Add documentation on making downward compatible changes
	to ali files so old tools work with new ali files.
	There is only one R line now.
	Add documentation on format incompatibilities (with special GPS note)

	* namet.ads, namet.adb: (Is_Operator_Name): New procedure

	* par-load.adb: Minor reformatting

	* sem_ch8.adb: Fix to error message from last update
	Minor reformatting and restructuring of code from last update

	* par-prag.adb, snames.adb, snames.ads, snames.h,
	sem_prag.adb: Implement pragma Profile.

	* stylesw.adb: Implement -gnatyN switch to turn off all style check
	options.

	* usage.adb: Add line for -gnatyN switch

	* vms_data.ads: Add entry STYLE_CHECKS=NONE for -gnatyN
