Thanks for the history.  I've investigated a bit after your email.
It seems that the pages were removed from glibc upstream in 2005 [1],
and then imported in the Debian glibc source package later in 2013 [2].
The last time a page's text was updated seems from 2002 by Drepper.

Yes, I plan to import these pages, specifying the historic details
found in this thread, keeping your name in the import commit, if you
don't mind, and then remove your name in the first commit, and start
cleaning them up.  I'd compare them to the POSIX pages, to see if
there's any obviously outdated stuff, and fix it.  Small details
that are not obvious from reading POSIX, I guess time will fix them.

So, you want your name removed.  Any other request?  The pages don't
seem to have a license.  Should GPL be applied to them as they were
once part of glibc?  If so, is GPL-3.0-or-later a good one?  Or
should I relicense as Linux-man-pages-copyleft?

Does the above plan look good to you?

Cheers,
Alex
