autoconf/automake versions needed for autoreconf

[Joel Sherrill]

Hi

I know I have asked this multiple times before. :(

I need to bootstrap to turn on libm/fenv. I am doing "autoreconf -fvi" from
libm. This looks like it might have worked but I get lots of scary output
using autoconf 2.69:

onfigure.in:11: error: support for Cygnus-style trees has been removed
Makefile.am:3: error: support for Cygnus-style trees has been removed
Makefile.am:5: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or
'*_CPPFLAGS')
Makefile.am: installing './INSTALL'
Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './README' not found
Makefile.am: error: required file './AUTHORS' not found
Makefile.am: error: required file './ChangeLog' not found
Makefile.am: installing './COPYING' using GNU General Public License v3 file
Makefile.am:     Consider adding the COPYING file to the version control
system
Makefile.am:     for your code, to avoid questions about which license your
project uses
automake: warning: autoconf input should be named 'configure.ac', not
'configure

It also replaced the top level config.guess and config.sub.

Is that the right command to bootstrap and what versions of autoconf and
automake should I be using?

Thanks.
