[multiple changes] 

2003-12-03  Thomas Quinot  <quinot@act-europe.fr>

	PR ada/11724

	* adaint.h, adaint.c, g-os_lib.ads:
	Do not assume that the offset argument to lseek(2) is a 32 bit integer,
	on some platforms (including FreeBSD), it is a 64 bit value.
	Introduce a __gnat_lseek wrapper in adaint.c to allow for portability.

2003-12-03  Arnaud Charlet  <charlet@act-europe.fr>

	* gnatvsn.ads (Library_Version): Now contain only the relevant
	version info.
	(Verbose_Library_Version): New constant.

	* g-spipat.adb, g-awk.adb, g-debpoo.adb,
	g-memdum.adb, g-thread.adb, s-geveop.adb, s-interr.adb,
	s-taskin.adb, s-tassta.adb: Make code compile with -gnatwa.

	* gnatlbr.adb: Clean up: replace Library_Version by
	Verbose_Library_Version.

	* make.adb, lib-writ.adb, exp_attr.adb:
	Clean up: replace Library_Version by Verbose_Library_Version.

	* 5lintman.adb: Removed.

	* Makefile.in:
	Update and simplify computation of LIBRARY_VERSION.
	Fix computation of GSMATCH_VERSION.
	5lintman.adb is no longer used: replaced by 7sintman.adb.

2003-12-03  Robert Dewar  <dewar@gnat.com>

	* exp_ch5.adb:
	(Possible_Bit_Aligned_Component): Maybe_Bit_Aligned_Large_Component new
	name. Modified to consider small non-bit-packed arrays as troublesome
	and in need of component-by-component assigment expansion.

2003-12-03  Vincent Celier  <celier@gnat.com>

	* lang-specs.h: Process nostdlib as nostdinc

	* back_end.adb: Update Copyright notice
	(Scan_Compiler_Arguments): Process -nostdlib directly.

2003-12-03  Jose Ruiz  <ruiz@act-europe.fr>

	* Makefile.in:
	When defining LIBGNAT_TARGET_PAIRS for bare board targets, remove the
	redundant inclusion of EXTRA_HIE_NONE_TARGET_PAIRS, which is always
	included in HIE_NONE_TARGET_PAIRS.

2003-12-03  Ed Schonberg  <schonberg@gnat.com>

	* sem_attr.adb:
	(Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
	is legal in an instance, because legality is cheched in the template.

	* sem_prag.adb:
	(Analyze_Pragma, case Warnings): In an inlined body, the pragma may be
	appplied to an unchecked conversion of a formal parameter.

	* sem_warn.adb:
	(Output_Unreferenced_Messages): Suppress "not read" warnings on imported
	variables.

2003-12-03  Olivier Hainque  <hainque@act-europe.fr>

	* tb-alvms.c (unwind_regular_code, unwind_kernel_handler): New
	routines. The second one is new functionality to deal with backtracing
	through signal handlers.
	(unwind): Split into the two separate subroutines above.
	Update the documentation, and deal properly with sizeof (REG) different
	from sizeof (void*).
