  comment:  Old Tcl scripts running on 8.6.x+ with corresponding Tcllib for crc32
            package produce a checksum.  Now with Tcl 9.0.1 and corresponding
            Tcllib the crc32 package do the same,  but for some file's content an
            error occur.

            Error message from "::crc::crc32" is "integer value too large to
            represent".  Problem seems to be inside of an operation of
            "::crc::Crc32Update" and/or "::crc::Crc32Final".  If You install BAWT
            3.0.1 64-Bit Tcl/Tk 9.0.1 for/on Windows 10/11,  You can check at
            least with the two following smallest files available:
            C:\\Tcl\\lib\\poTcllib3.0.0\\poExec.tcl 2024-08-16 20:26:04 4108
            C:\\Tcl\\lib\ cllib2.0\\valtype\\luhn5.tcl 2024-09-13 19:48:12 4121

            Both files have correct UTF-8 encoding with simple UNIX-LF.  So there
            is another reason for this problem than the encoding of the file's
            contents.  (My first thinking is therefore wrong and I changed this
            description.)  Can anybody debug deeper into this?

            Simple test in Tcl:  package require crc32  ::crc::crc32 -filename
            "C:/Tcl/lib/tcllib2.0/valtype/luhn5.tcl"

            I use on ActiveTcl 8.6.4.1 crc32 1.3.2 and found it on
            BAWT-distribution 3.0.1,  Tcllib 2.0, crc32 1.3.4 thanks.

            Best greetings, Thomas [TWu]
