Arnaud Charlet b3c336413b [multiple changes]
2011-10-24  Robert Dewar  <dewar@adacore.com>

	* sem.adb (Initialize): Fix bug that blew up if called a second
	time.

2011-10-24  Robert Dewar  <dewar@adacore.com>

	* tb-alvxw.c, tracebak.c, expect.c, initflt.c, tb-alvms.c,
	tb-ivms.c, tb-gcc.c: Update headers to GPL 3.

2011-10-24  Robert Dewar  <dewar@adacore.com>

	* sem_prag.adb (Analyze_Pragma, case Debug): Give proper pragma
	name in error msg.

2011-10-24  Hristian Kirtchev  <kirtchev@adacore.com>

	* gnat_rm.texi Add an entry for restriction No_Finalization.

2011-10-24  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Insert_Freeze_Node_For_Instance):  If the
	current instance is within the one that contains the generic,
	the freeze node for the current one must appear in the current
	declarative part. Ditto if the current instance is within another
	package instance. In both of these cases the freeze node of the
	previous instance is not relevant.

2011-10-24  Gary Dismukes  <dismukes@adacore.com>

	* switch-m.adb (Normalize_Compiler_Switches): Add recognition
	of AAMP-specific switches -univ and -aamp_target.

2011-10-24  Robert Dewar  <dewar@adacore.com>

	* a-tienau.adb (Put): Deal properly with limited line length.

2011-10-24  Robert Dewar  <dewar@adacore.com>

	* sem_warn.adb, sem_ch12.adb: Minor reformatting.
