        * TODO: Remove already done things.  Update the part
        about finding tools for the target.

2003-11-24  Paolo Bonzini <bonzini@gnu.org>

        * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
        AC_DIR_HEADER): Make wording more consistent.
        * lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2,
        AC_MINGW32): Explain the transition better.
        * lib/autoconf/types.m4 (AC_INT_16_BITS,
        AC_LONG_64_BITS): Explain the transition better.

2003-11-24  Paolo Bonzini  <bonzini@gnu.org>

        * doc/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.

 It would be nice if I could (in the Makefile.in files) set
 the path to config.h. You have config.h ../config.h ../../config.h's all
 over the place, in the findutils-4.1 directory.
