-@cindex obsolete macros
-@cindex autoupdate
-
-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!}

-@table @code
-
-@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 This macro is obsolete, you should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.
-
-@item AM_SYS_POSIX_TERMIOS
-@acindex AM_SYS_POSIX_TERMIOS
-@cindex POSIX termios headers
-@cindex termios POSIX headers
-Check to see if POSIX termios headers and functions are available on the
-system. If so, set the shell variable @code{am_cv_sys_posix_termios} to
-@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 This macro is obsolete,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.
