 ** Fix the `m4wrap' builtin to accumulate wrapped text in FIFO order, as
    required by POSIX.  The manual mentions a way to restore the LIFO order
    present in earlier GNU M4 versions.  NOTE: this change exposes a bug
-   in Autoconf 2.59 and earlier (which was fixed in Autoconf 2.60).  If
-   you still need to use older autoconf, then add these lines to your
-   project's configure.ac, prior to calling AC_INIT:
+   in Autoconf 2.59 and earlier (which was fixed in Autoconf 2.60).
+
+   If you want your package to work with pre-installed Autoconf without
+   requiring 2.60, then add these lines to your project's configure.ac,
+   prior to calling AC_INIT:
+
      # As long as this project is not ready to upgrade to autoconf 2.60
      # or newer, make sure that newer M4 will still use LIFO order:
-     m4_define([m4_wrap],
-       [m4_ifdef([_$0_text],
-         [m4_define([_$0_text], [$1]m4_defn([_$0_text]))],
-         [m4_define([_$0_text], [$1])m4_builtin([m4wrap],
-           [m4_default(m4_defn([_$0_text])m4_undefine([_$0_text]))])])])
+     m4_define([m4_wrap], [m4_ifdef([_$0_text],
+       [m4_define([_$0_text], [$1]m4_defn([_$0_text]))],
+       [m4_define([_$0_text], [$1])m4_builtin([m4wrap],
+         [m4_default(m4_defn([_$0_text])m4_undefine([_$0_text]))])])])
+
+   On the other hand, if you want to install Autoconf 2.59 or earlier,
+   then apply this patch:
+     http://git.sv.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=56d42fa71
 
 ** Enhance the `ifdef', `ifelse', and `shift' builtins, as well as all
    user macros, to transparently handle builtin tokens generated by `defn'.
