new snapshot available: m4-1.4.19.65-bdd9.tar.xz

I plan to release stable m4-1.4.20 in the next few days; either
directly (if this snapshot gets good testing) or with an intermediate
wider release of beta 1.4.19b.  I've already had some good feedback on
my previous snapshot 1.4.19.60-6ebfc; but there were enough changes
that I have posted another snapshot rather than triggering the
release.  Any testing you can do on various different systems between
now and then would be most welcome.  This release comes several years
after 1.4.19, and is mainly a bug fix release.

--------------------------------------

You can download the M4 snapshot in xz format (2.0 MiB) from:
         https://people.redhat.com/eblake/m4/m4-1.4.19.65-bdd9.tar.xz

And verify with gpg or md5sum with:
         https://people.redhat.com/eblake/m4/m4-1.4.19.65-bdd9.tar.xz.sig
         MD5 (m4-1.4.19.65-bdd9.tar.xz) = 9a86bdadd5950e99d0496fad5424aec2

--------------------------------------

To test, follow this standard procedure:

         tar -xf m4-1.4.19.65-bdd9.tar.xz
         cd m4-1.4.19.65-bdd9/
         ./configure && make check VERBOSE=yes

If this fails in subdirectory checks/, then the build of M4 itself is
likely broken; if the check moves on to tests/, then details in
tests/test-suite.log for any failures will help us improve the
portions of gnulib used by M4.
