The headers on most of these files indicate that glibc is the canonical source for these files, although in many cases there seem to be useful changes in the gnulib versions that could be merged back in. Not all gnulib files contain such a header and it is not always consistent in its format, so it would be useful to make sure that all gnulib files that are using glibc as upstream have a greppable header.
These files are quite hard to find without a header to grep for and each file has to be compared manually so this list is likely incomplete or may contain errors.
GMP
The following files are shared with the GNU multi-precision arithmetic library.

The most recent update of the files in stdlib seems to have been in 1996 from GMP 2.0.
commit b928942eaa0401de9189a2709188f584425f5ca6
Author: Roland McGrath <roland@gnu.org>
Date: Tue May 7 21:04:52 1996 +0000
Updated from /src/gmp-2.0For these files GMP seems to be considered the upstream. The sysdeps files are updated independently and are from various different versions of GMP.
GMP since version 6 is licensed under LGPLv3 or GPLv2 which may pose problems with moving code from one project to the other.
gettext
The following files are shared with the GNU gettext library.
intl/bindtextdom.c intl/dcgettext.c intl/dcigettext.c intl/dcngettext.c intl/dgettext.c intl/dngettext.c intl/explodename.c intl/finddomain.c intl/gettext.c intl/gettextP.h intl/gmo.h intl/hash-string.c intl/hash-string.h intl/l10nflist.c intl/loadinfo.h intl/loadmsgcat.c intl/locale.alias intl/localealias.c intl/ngettext.c intl/plural-exp.c intl/plural-exp.h intl/plural.y intl/textdomain.c
The last merge was 2014-12-11 and merged gettext 0.19.3 into glibc with a patch submitted to the gettext mailing list for changes that could be merged back.
This commit was omitted from the merge as it does not appear to be compatible with how glibc expects things to work:
commit 279b57fc367251666f00e8e2b599b83703451afb
Author: Bruno Haible <bruno@clisp.org>
Date: Fri Jun 14 12:03:49 2002 +0000
Make absolute pathnames inside $LANGUAGE work.
BIND
Some files in the hesiod and resolv directories originally came from BIND 4.
The last major update of these files was to BIND 8.2.3-T5B in July 2000.
BIND no longer comes with the BIND 4 stub resolver code, so there is no upstream for the glibc sources left.
The sources taken originally from BIND will be modified by glibc to meet the needs of its users.
ptmalloc2/dlmalloc
The following files are shared with ptmalloc2, which is derived from dlamlloc.
malloc/arena.c malloc/malloc.c
ptmalloc2 upstream is dead and the code has changed considerably since the last ptmalloc2 release, but dlmalloc still sees occasional updates. It's not clear if the changes to dlmalloc could be ported back to glibc or if that would be beneficial.
Unicode
The following files are shared with the upstream Unicode project and must be updated regularly to stay in sync with the upstream unicode releases.
