Hi Stefano,
Here's the promised patch.
This is relative to "master" and "make check" still passes.
I have spent too little time investigating the merge conflicts,
so odds are good that you'll find more than nits to pick.

Subject: [PATCH] reinstate AM_PROG_MKDIR_P
Do not remove AM_PROG_MKDIR_P just yet.
gettext (latest from git) still AC_REQUIRE's AM_PROG_MKDIR_P via its
intl.m4 and po.m4 files, which are pulled into *many* projects.
When I try to build one of those projects (coreutils) using the latest
from automake.git/master, I see this failure:
$ aclocal -I m4
configure.ac:477: warning: AM_PROG_MKDIR_P is m4_require'd \
but not m4_defun'd
m4/po.m4:23: AM_PO_SUBDIRS is expanded from...
m4/gettext.m4:57: AM_GNU_GETTEXT is expanded from...
configure.ac:477: the top level
That is because AM_PROG_MKDIR_P was removed (via commit
v1.12-20-g8a1c64f) in preparation for the next release of automake.
* NEWS: Remove the paragraph that announced the removal of
AM_PROG_MKDIR_P.
* Makefile.am (dist_automake_ac_DATA): Add m4/mkdirp.m4.
* m4/mkdirp.m4: Re-add file.
* t/mkdirp-deprecation.sh: Likewise.
* t/list-of-tests.mk: Add it.
* automake.in: Restore removed code, and adjust comments, s/1.13/1.14/
to reflect new plan for removal.
* doc/automake.texi (Obsolete Macros): Restore deleted section.

+Although using some of the following macros was required in past
+releases, you should not use any of them in new code. @emph{All
+these macros will be removed in the next major Automake version};
+if you are still using them, running @command{autoupdate} should
+adjust your @file{configure.ac} automatically (@pxref{autoupdate
+Invocation, , Using @command{autoupdate} to Modernize
+@file{configure.ac}, autoconf, The Autoconf Manual}).
+@emph{Do it NOW!}

+@item AM_CONFIG_HEADER
+@acindex AM_CONFIG_HEADER
+Automake will generate rules to automatically regenerate the config
+header. This obsolete macro is a synonym of @code{AC_CONFIG_HEADERS}
+today (@pxref{Optional}).
+
+@item AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL
+@acindex AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL
+If the use of @code{TIOCGWINSZ} requires @file{<sys/ioctl.h>}, then
+define @code{GWINSZ_IN_SYS_IOCTL}. Otherwise @code{TIOCGWINSZ} can be
+found in @file{<termios.h>}. This macro is obsolete, you should
+use Autoconf's @code{AC_HEADER_TIOCGWINSZ} instead.
+
+@item AM_PROG_MKDIR_P
+@acindex AM_PROG_MKDIR_P
+@cindex @code{mkdir -p}, macro check
+@vindex MKDIR_P
+@vindex mkdir_p
+
+From Automake 1.8 to 1.9.6 this macro used to define the output
+variable @code{mkdir_p} to one of @code{mkdir -p}, @code{install-sh
+-d}, or @code{mkinstalldirs}.
+
+Nowadays Autoconf provides a similar functionality with
+@code{AC_PROG_MKDIR_P} (@pxref{Particular Programs, , Particular
+Program Checks, autoconf, The Autoconf Manual}), however this defines
+the output variable @code{MKDIR_P} instead. In case you are still
+using the @code{AM_PROG_MKDIR_P} macro in your @file{configure.ac},
+or its provided variable @code{$(mkdir_p)} in your @file{Makefile.am},
+you are advised to switch ASAP to the more modern Autoconf-provided
+interface instead; both the macro and the variable @emph{will be
+removed} in the next major Automake release.

+@acindex AM_SYS_POSIX_TERMIOS

+Check to see if POSIX termios headers and functions are available on the

+@samp{yes}. If not, set the variable to @samp{no}. This macro is obsolete,
+you should use Autoconf's @code{AC_SYS_POSIX_TERMIOS} instead.
