verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective

+2001-12-23  Richard Henderson  <rth@redhat.com>
+
+	* utils.c (end_subprog_body): Push GC context around
+	rest_of_compilation for nested functions.
+
+2001-12-23  Richard Henderson  <rth@redhat.com>
+
+	* 5nosinte.ads: Get definition of "int" from Interfaces.C.
+
+2001-12-23  Florian Weimer  <fw@deneb.enyo.de>
+
+	* gnat-style.texi (Declarations and Types): Remove ancient style
+	rule which was mandated by code generation issues.
+
+	* gnat-style.texi (header): Add @dircategory, @direntry.
+	(title page): Remove date.
+	(general) Add @./@: where approriate, and two spaces after the
+	full stop at the end of a sentence.  Use @samp markup when
+	referring concrete lexical entities (keywords, attribute names
+	etc.), and @syntax for ARM grammar elements. Use @r for English
+	text in comments.  Use @emph for emphasis.  Change "if-statements"
+	etc. to "if statements" (without @samp). Break long lines.  Make
+	casing of section names consistent.
+	(Identifiers): Use @samp markup for variable names.
+	(Comments): Use @samp markup for comment characters. Line-end
+	comments may follow any Ada code, not just statements.  Fix
+	misspelling of "Integer" as "integer".
+	(Loop statements): Do not use variable name "I", use "J".
+	(Subprogram Declarations): Document alignment.
+	(Subprogram Bodies, Block statements): Document empty line before
+	"begin".

+
+	* make.adb (Add_Switch): Make Generic_Position a procedure.  The
+	function approach did not work well because of a side effect (the

+
+	* scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
+	GNAT.CRC32).  Update copyright notice.
+
+	* scn-slit.adb: Rename many Accumulate_Checksum to Update (from
+	GNAT.CRC32).  Update copyright notice.
+
+	* scn.adb:
+	(Accumulate_Checksum): removed.
+	(Update): new procedure. Add a wide-character into the CRC.
+
+	* sinput-l.adb:
+	(Complete_Source_File_Entry): use CRC32 instead of simple checksum.
+	(Load_File): fix initialization of S (change Source_Checksum to
+	Source_CRC)
+
+	* sinput-p.adb (Load_Project_File): rename Source_Checksum to
+	Source_CRC in S initialization.
+
+	* sinput.adb (Source_Checksum): renamed to Source_CRC.
+
+	* sinput.ads (Source_Checksum): renamed to Source_CRC.
+	Update comments for the CRC.
+
+	* types.adb (Hex): Use lowercase for the letter part.
+
+	* types.ads (Get_Hex_String): Returns the hexadecimal representation
+	for a word. This is currently used only for CRC. In previous version,
+	the checksum was using a representation with all letter being
+	upper-case. With the new implementation (using CRC) we do not remove
+	the 32th bit of the CRC, so we can have an upper-case starting letter
+	in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
+	It is ambigous since the CRC was optional and could be followed by
+	options like EB, EE. So now this routines uses lower-case letter for
+	the hexadecimal representation. Strange enough only lower case letters
+	where checked in Scan_ALI (even if this was not a possible case).
+
+	* gnatvsn.ads (Library_Version): changed to 3.15a.
+
+	* s-crc32.ads: Initial version from GNAT.CRC32. This is the version

+	for the compiler.

+	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
+	Add 2001 to copyright notice
+	(Accumulate_Checksum): Modify to use System.CRC32.
+
+	* ali-util.ads: Redo changes of previous revision to continue to use
+	the word Checksum. Add 2001 to copyright notice.
+
+	* ali.adb: Undo some of previous changes, not needed.
+	Keep the change for lower case letters in the checksum.
+
+	* ali.ads: Undo previous change not needed.
+
+	* bcheck.adb: Undo most of previous change, not needed.
+	But do use Checksums_Match for checksum comparison.

+	* sinput.adb: Undo previous change, not needed.
+
+	* sinput-l.adb: Undo previous change, not needed.
+
+	* sinput.ads: Undo previous change, not needed.  Keep only comment
+	on new checksum algorithm
+
+	* Makefile.in: Add s-crc32 as needed, remove g-crc32.

+
+	* ali.adb (Scan_ALI): fix typo introduce in latest check-in.
