That amd64 package (5.04-1.0.0.1.pure64) may have been
created by Christopher L Cheney. changes file for it
has the "Changed-By" line.

Maybe. I'll consult it with the upstream later.
# When the extipl began to use __llseek on linux,
# there are both of libc5 systems and glibc2 systems.
# So __llseek was the simplest way at that time,
# or it seemed that, at least.
# Now I hope that we can use lseek64 on most of linux systems,
# can't we ?
