Ravenbrook Limited

Generic 2.2.8 PC.
>Description:
/usr/bin/wc overflows at 2^32, so passing it a big file
(or stream) gives bogus results.
>How-To-Repeat:
$ dd if=/dev/zero bs=1m count=4097 | wc
4097+0 records in
4097+0 records out
4296015872 bytes transferred in 614.248991 secs (6993932 bytes/sec)
1048576
$
>Fix:
I'm sure a simple hack in the wc sources could make the
counters 64-bit.
