Version 2.57d.

Version 2.57d.
* bin/Makefile.am (edit): Handle '@configure_input@'.
(autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
(ifnames): chmod -w.
* tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
executables, not bin/ executables!  Otherwise all the magic needed
to find non installed files is turned off.  This caused a failure
of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
as found in its environment (sent by tests/autoreconf): pointing
to bin/autom4te that could not find its files.
* tests/mktests.sh: Force the replacement of generated files, for
the sake of "mv" program that are interactive when overwriting a
-w file.
* config/install-sh: Upgrade from CVS Automake.
