with autoconf 2.53:

  gdt gdt 111 ~/SOFTWARE/CODA/coda > autoconf
  configure.in:4: error: m4_defn: undefined macro: _m4_divert_diversion
  autoconf/general.m4:479: AC_PREFIX_DEFAULT is expanded from...
  configure.in:4: the top level

removing AC_PREFIX_DEFAULT seems to help:

  gdt gdt 114 ~/SOFTWARE/CODA/coda > ./bootstrap.sh 
  WARNING: Using auxiliary files such as `acconfig.h', `config.h.bot'
  WARNING: and `config.h.top', to define templates for `config.h.in'
  WARNING: is deprecated and discouraged.

  WARNING: Using the third argument of `AC_DEFINE' and
  WARNING: `AC_DEFINE_UNQUOTED' allows to define a template without
  WARNING: `acconfig.h':

  WARNING:   AC_DEFINE([NEED_MAIN], 1,
  WARNING:             [Define if a function `main' is needed.])

  WARNING: More sophisticated templates can also be produced, see the
  WARNING: documentation.
  autoheader: `config.h.in' is updated

So perhaps this should be removed if not still necessary, or moved
after the init statement.
