FYI: remove documentation for AU_DEFUN's third parameter

The third parameter did not work anymore; it was passed AC_DEFUN from which it went into oblivion. Only AC_LINK_FILES still used it, so I moved the warning to the expanded body as done by AC_USG, AC_CYGWIN and other macros.

Committed as obvious, regtested together with the other two patches.

2003-11-24  Paolo Bonzini  <address@hidden>

        * doc/autoconf/autoconf.texi (Obsoleting Macros): Don't
        document the third parameter of AU_DEFUN.
        * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
        (AU_DEFUN): Remove the third parameter, it was not used.
        Use AC_DEFUN directly, not AU_DEFINE.
        * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message
        into the expanded body, consistently with other macros
        such as AC_USG.
