+Subject: [PATCH] build: Use a minimum gettext requirement rather than an exact
+ one
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In configure.ac, specify the minimum gettext version we require, rather
+than the exact one. This fixes a situation where the autoconf macros
+used for gettext will be the latest available on the system (for
+example, 0.19); but the copied-in Makefile.in.in will be for the exact
+version specified in configure.ac (in this case, 0.18).
+
+In that situation, the gettext build rules will error out at `make` time
+with the message:
+   *** error: gettext infrastructure mismatch: using a Makefile.in.in
+   from gettext version 0.18 but the autoconf macros are from gettext
+   version 0.19
+
+Avoid that by specifying a minimum version dependency rather than an
+exact one. This should not cause problems as we haven’t committed any
+generated or external gettext files into git, so each developer will end
+up regenerating the build system for their system’s version of gettext,
+as expected.
+
+See the subsection of
+https://www.gnu.org/software/gettext/manual/html_node/Version-Control-Issues.html
+for more information.
+
+Note that autoreconf currently doesn’t recognise
+AM_GNU_GETTEXT_REQUIRE_VERSION, so we must continue also using
+AM_GNU_GETTEXT_VERSION. autopoint will ignore the latter if the former
+is present. See
+https://lists.gnu.org/archive/html/autoconf-patches/2015-10/msg00000.html.
