	* a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi
	with 192 bits of precision, sufficient to reduce a double-extended
	arguments X with a maximum relative error of T'Machine_Epsilon, for X
	in -2.0**32 .. 2.0**32.
	(Cos, Sin):  Always reduce arguments of 1/4 Pi or larger, to prevent
	reduction by the processor, which only uses a 68-bit approximation of
	Pi.
	(Tan): Always reduce arguments and compute function either using
	the processor's fptan instruction, or by dividing sin and cos as needed.

2004-05-24  Doug Rupp  <rupp@gnat.com>

	* adaint.c (__gnat_readdir): Cast CRTL function retun value to avoid
	gcc error on 32/64 bit VMS.

2004-05-24  Olivier Hainque  <hainque@act-europe.fr>

	* init.c (__gnat_error_handler): Handle EEXIST as EACCES for SIGSEGVs,
	since this is what we get for stack overflows although not documented
	as such.
	Document the issues which may require adjustments to our signal
	handlers.

2004-05-24  Ed Schonberg  <schonberg@gnat.com>

	* inline.adb (Add_Scope_To_Clean): Do not add cleanup actions to the
	enclosing dynamic scope if the instantiation is within a generic unit.

2004-05-24  Arnaud Charlet  <charlet@act-europe.fr>

	* exp_dbug.ads: Fix typo.

	* Makefile.in: s-osinte-linux-ia64.ads was misnamed.
	Rename it to its proper name: system-linux-ia64.ads
	(stamp-gnatlib1): Remove extra target specific run time files when
	setting up the rts directory.

2004-05-24  Javier Miranda  <miranda@gnat.com>

	* einfo.ads, einfo.adb (Limited_Views): Removed.
	(Limited_View): New attribute that replaces the previous one. It is
	now a bona fide package with the limited-view list through the
	first_entity and first_private attributes.

	* sem_ch10.adb (Install_Private_With_Clauses): Give support to
	limited-private-with clause.
	(Install_Limited_Withed_Unit): Install the private declarations of a
	limited-private-withed package. Update the installation of the shadow
	entities according to the new structure (see Build_Limited_Views)
	(Build_Limited_Views): Replace the previous implementation of the
	limited view by a package entity that references the first shadow
	entity plus the first shadow private entity (required for limited-
	private-with clause)
	(New_Internal_Shadow_Entity): Code cleanup.
	(Remove_Limited_With_Clause): Update the implementation to undo the
	new work carried out by Build_Limited_Views.
	(Build_Chain): Complete documentation.
	Replace Ada0Y by Ada 0Y in comments
	Minor reformating

	* sem_ch3.adb (Array_Type_Declaration): In case of anonymous access
	types the level of accessibility depends on the enclosing type
	declaration.

	* sem_ch8.adb (Find_Expanded_Name): Fix condition to detect shadow
	entities. Complete documentation of previous change.

2004-05-24  Robert Dewar  <dewar@gnat.com>

	* namet.adb: Minor reformatting
	Avoid use of name I (replace by J)
	Minor code restructuring

	* sem_ch6.adb: Minor reformatting

	* lib-writ.adb: Do not set restriction as active if this is a
	Restriction_Warning case.

	* sem_prag.adb: Reset restriction warning flag if real pragma
	restriction encountered.

	* s-htable.adb: Minor reformatting
	Change rotate count to 3 in Hash (improves hash for small strings)

	* 5qsystem.ads: Add comments for type Address (no literals allowed).

	* gnat_ugn.texi: Add new section of documentation "Code Generation
	Control", which describes the use of -m switches.

2004-05-24  Eric Botcazou  <ebotcazou@act-europe.fr>

	(tree_transform) <N_Identifier>: Do the dereference directly through
	the DECL_INITIAL for renamed variables.
