Hi Bill,
Thanks for the thought provoking questions.

Yes, I did get them. I assumed they were harmless/just warnings because
dh-autoreconf finished with success and the package test-suite passed.
But then..
> [...] Do you know what they mean ?
Well, now I do. Since you asked, I investigated them a bit.. and that
assumption looks correct.
This message is just a warning, harmless:
main::scan_file() called too early to check prototype at
/usr/bin/aclocal-1.11 line 643.
It was fixed upstream on automake 1.12.1, but not on 1.11 (unnoticed on
Debian as automake1.11 has the test-suite disabled). Just in case, I
submitted #752784, but the difference in dh-autoreconf's result with/
without the fix is effectively null (see its message 10).
These messages from libtoolize are harmless too:
libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, `.'.
libtoolize: copying file `./ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac
and
libtoolize: rerunning libtoolize, to keep the correct libtool macros
in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
If you implement the suggested considerations from libtoolize, it will
just copy the libtool macros as individual files in the m4/ dir.
If you don't (as it is), it will just copy the contents of those files
in aclocal.m4 (next e-mail) -- with identical results.
Since both cases work fine, and dh_autoreconf_clean will clean-up that
output anyway, I would not bother with carrying a new patch only for
silencing a warning from libtoolize (and creating empty m4/ dir, so to
avoid an aclocal error due to '-I m4/', populated by libtoolize later).
For your convenience, I attached that patch, nonetheless.
I hope this clarifies those questions.
Would the patch(es) be good to go, then?
Thanks!
