[multiple changes] 

2003-12-05  Thomas Quinot  <quinot@act-europe.fr>

	* 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,
	version of this unit).

2003-12-05  Olivier Hainque  <hainque@act-europe.fr>

	* 53osinte.ads, 54osinte.ads, 55osinte.ads, 56osinte.ads, 5bosinte.ads,
	5cosinte.ads, 5hosinte.ads, 5iosinte.ads, 5losinte.ads,
	5tosinte.ads: Define the SA_SIGINFO constant, to allow references from
	the body of System.Interrupt_Management common to several targets.
	Update copyright notice when appropriate.

	* 52osinte.ads, 5posinte.ads: Define a dummy value for the SA_SIGINFO
	constant.

	* 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
	to ensure that the kernel fills in the interrupted context structure
	before calling a signal handler, which is necessary to be able to
	unwind past it. Update the copyright notice.

2003-12-05  Jerome Guitton  <guitton@act-europe.fr>

	* a-elchha.ads: New file.

	* a-elchha.adb: New default last chance handler. Contents taken from
	Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.

	* a-exextr.adb (Unhandled_Exception_Terminate): Most of this routine
	is moved to a-elchha.adb to provide a target-independent default last
	chance handler.

	* Makefile.rtl: Add a-elchha.o

	* Make-lang.in (GNAT_ADA_OBJS, GNATBIND_OBJS): Add a-elchha.o.

2003-12-05  Ed Schonberg  <schonberg@gnat.com>

	* exp_ch6.adb (Expand_Call): If the subprogram is inlined and is
	declared in an instance, do not inline the call if the instance is not
	frozen yet, to prevent order of elaboration problems.

	* sem_prag.adb: Add comments for previous fix.

2003-12-05  Samuel Tardieu  <tardieu@act-europe.fr>

	* g-table.adb: Use the right variable in Set_Item.
	Update copyright notice.

2003-12-05  Arnaud Charlet  <charlet@act-europe.fr>

	* Makefile.in: Remove unused rules.

2003-12-05  Vincent Celier  <celier@gnat.com>

	* switch-c.adb (Scan_Front_End_Switches): Remove processing of
	-nostdlib. Not needed here after all.
