Patch below.  I also added a section on the development tools that are
required, to document the version requirement on autoconf.

There isn't.  I tried everything more reasonable first; there really is
no better way to handle this problem.

  are very simple and hopefully should make for a more orderly development
  of zsh.
  
+ Tools
+ -----
+ 
+ To develop (as opposed to just build) zsh, you'll need a few specialised
+ tools:
+ 
+ * GNU autoconf, version 2.12 or later.  (Earlier versions mostly work,
+   but part of the configuration system now relies on part of the format
+   of the config.status files that get generated.  See the comments in
+   configure.in and at the end of Src/mkmakemod.sh for an explanation.)
+ 
+ * GNU m4.  (Required by autoconf.)
+ 
+ * yodl.
+ 
+ * texi2html.
