My suggestion would be to consider any recommended action that triggers a "this
is obsolete" message to be a bug.  The fix might belong in the docs,
it might belong
in not construing something obsolete or it might be to internally suppress the
warning.  Wherever the fix belongs, it is unlikely that the person
stubbing their toe
on it is going to have a best guess as to where it belongs.

I've suggested, but I'll suggest a patch once I've pounded my way through
this "libposix" thing.

Nice!  I noticed I didn't see all those messages last time I rolled up
a sharutils distro.

No, the create-testdir worked, but it did not produce a project that could be
rolled up and distributed.  I would not expect it to.  I am tweaking the result
with the following:

1.  version.[ch] and basing it off of the first date found in
gnulib/ChangeLog :)
2.  replacing libgnu.a with libposix.la
3. installing all the headers (see Makefile.am edits below)
4. fixing AC_INIT() in configure.ac
5. removing libtool conditionality -- making it required

I'm not done yet, so there may be more.  I'm doing it all with a single file --
a shell script that does everything.  It presumes itself to be living in a
subdirectory within gnulib.  Anyway, my current state:

Finally, the Makefile.am edits:

    sed -i -e "/^EXTRA_DIST *= *$/s/$/ version.[ch]/" \
        -e "/^noinst_LTLIB/d" \
        -e "/^noinst_LIBRARIES/s/noinst_L/lib_LTL/g" \
        -e "/noinst_HEADERS/s/noinst_H.*/nobase_include_HEADERS = \\\\/" \
        -e "/^nobase_include_HEADERS =/a${headerlist}" \
        -e "s/^libgnu_a_SOURCES *=.*/${TARNAME}_la_SOURCES = version.c/g" \
        -e "s/libgnu_a_/${TARNAME}_la_/g" \
        -e "/^lib_LTLIBRARIES *=/s/=.*/= ${TARNAME}.la/" \
        -e "/^lib_LTLIBRARIES *+/d" \
        -e "s/libgnu\\.a/libposix.la/" \
        Makefile.am
