        * sem_eval.adb: (Constant_Array_Ref): Verify that constant
        value of array exists before retrieving it (it may a private
        protected component in a function).

        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.

        function approach did not work well because of a side effect (the
        function call could reallocate the table which was being indexed
        using its result). Fixes ada/4851.

        as exception message.

        exception handler, always use new transient scope to place Clean
        procedure.

2001-10-11  Pascal Obry <obry@gnat.com>

        * Makefile.in:
        (GNAT_ADA_OBJS): add g-crc32.o, a-tags.o, a-stream.o
        (GNATBIND_OBJS): add g-crc32.o, a-tags.o, a-stream.o
        (GNATLS_RTL_OBJS): add g-crc32.o
        (GNATMAKE_RTL_OBJS): add g-crc32.o

        * ali-util.adb:
        (CRC_Match): new function.
        (Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
        instead of the previous simple checksum algorithm.
        (Time_Stamp_Mismatch): use CRC_Match for comparison.
        (Set_Source_Table): idem.

        * ali-util.ads:
        (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
        instead of simple checksum.
        (CRC_Match): new function.
        (CRC_Error): new constant.

        * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
        a CRC now and not a simple checksum. A CRC uses lower-case hex
        letters, fixes ambiguity in parsing.

        * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
        is what this variable will store.

        * bcheck.adb: Change reference to chechsum in comments by CRC.
        (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
        rename All_Checksum_Match to All_CRC_Match. Change due to API
        renaming since now GNAT does not use a simple checksum but a
        CRC using GNAT.CRC32.

        * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
        now and not anymore a simple checksum.

        * lib-load.adb: Use Source_CRC instead of Source_Checksum in many
        places.

        * lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.

        * scans.adb:
        (Restore_Scan_State): rename Checksum to CRC.
        (Save_Scan_State): idem.

        * scans.ads:
        With GNAT.CRC32.
        (Checksum): rename to CRC.
        (Saved_Scan_State): Save_Checksum field renamed to Save_CRC

        * 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.

        * s-crc32.adb: 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.

        * gnatls.adb: Undo most of previous change, not needed.
        But do use Checksums_Match for comparing checksums.

        * lib-load.adb: Undo previous change, not needed.

        * lib-writ.adb: Undo previous change, not needed.

        * lib-writ.ads: Document that checksums use lower case,
        not upper case letters.

        * scans.adb: Undo previous change, not needed

        * scans.ads: Undo previous change, not needed.

        * scn-nlit.adb: Undo previous changes, not needed.

        * scn.adb:
        (Accumulate_Checksum): Use System.CRC32.
        (Initialize_Checksum): New procedure.
        Remove other changes of previous revision.

        * sinput-p.adb: Undo previous change, not needed.

        * 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.
        Also remove a-tags and a-stream from GNAT sources.

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

        * Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
