Oh, great, thanks :-)

We don't use libc 2.0 on Sparc and I haven't build it on i386, so no.

AFAIK yes.

Just grab the latest lsof sources from ftp.debian.org or a mirror
/debian/dists/slink/main/source/utils/lsof_4.37.tar.gz
and try to build it under glibc2.1.

Sorry, my statement was unclear: There was a correction in the glibc2.1 linux
specific headers taken from 2.1.126 to get in line with the kernel headers.

What's the railroad to me ?
I never go to see
Where it ends.
It fills a few hollows,
And makes banks for the swallows,
It sets the sand a-blowing,
And the blackberries a-growing.
(Henry David Thoreau)
