[removed autoconf-patches from the cc list]

Hello all,
 I'm answering the easy questions to save some of Paul's time.

ok, then grab the tarball of the Autoconf you use today, apply the
patch attached to this mail (applies cleanly to 2.61 and with some
offset to 2.60).  Then configure with some --prefix, install, enjoy.

(The version number will stay the same, but I do not think we should
be that strict, it's just a wording of a message, after all.)

Alternatively, place this definition to configure.ac, _before_
AC_INIT:

m4_define([_AS_SHELL_FN_SPY],
[_AS_DETECT_SUGGESTED([_AS_SHELL_FN_WORK])
_AS_RUN([_AS_SHELL_FN_WORK]) || {
  echo No shell found that supports shell functions.
  echo Please tell bug-autoconf@gnu.org about your system,
  echo including any error possibly output before this message.
  echo This can help us improve future autoconf versions.
  echo Configuration will now proceed without shell functions.
}
])

(Remember to replace that by AC_PREREQ([2.62]) when both your and our
releases are out.)

> [...] or just applying the same change directly to the configure file.

That's a way, too.  Just replace the text in the generated configure
by the new one.  (There is only one occurence.)

Happy hacking,
	Stepan
