those functions are available. This problem does not exist with
releases 1.06 and later of the GNU C library, which define C
-preprocessor macros that the Autoconf macros @code{AC_FUNC_CHECK} and
+preprocessor macros that the Autoconf macros @code{AC_CHECK_FUNC} and
@code{AC_REPLACE_FUNCS} test, indicating that certain functions are
stubs (@pxref{C Features}, for more information on checking for
functions).

+The @code{autoupdate} program updates a @file{configure.in} file that
+calls Autoconf macros by their old names to use the current macro names.
+In version 2 of Autoconf, most of the macros were renamed to use a more
+uniform and descriptive naming scheme. Although the old names still
+work (@pxref{Old Macro Names}, for a list of the old macro names and the
+corresponding new names), you can make your @file{configure.in} files
+more readable and make it easier to use the current Autoconf
+documentation if you update them to use the new macro names.
+
+If given no arguments, @code{autoupdate} updates @file{configure.in},
+backing up the original version in the file @file{configure.in~}. If
+you give @code{autoupdate} an argument, it reads that file instead of
+@file{configure.in} and writes the updated file to the standard output.

+@itemx -m @var{dir}
+Look for the Autoconf macro files in directory @var{dir} instead of the
+default installation directory.

Add @samp{-traditional} to @code{make} variable @code{CC} if using the
