Hi Gary,

I've put autoconf-patches back in -- they are the target of this.  :)

Surely.  I'm not volunteering for the documentation patches, but here is
a preliminary list of macros used by Libtool macros (no guarantees, I
only did a casual search for m4_*):

not defined in autoconf.texi:
m4_append
m4_bmatch
m4_car
m4_case
m4_cdr
m4_defun
m4_fatal
m4_foreach
m4_ifndef
m4_ifset
m4_ifval
m4_n
m4_normalize
m4_require
m4_shiftn
m4_split
m4_toupper
m4_version_compare

not defined in autoconf.texi, but listed in m4.texi (renamed m4 builtins):
m4_ifdef
m4_pushdef

mentioned in autoconf.texi, but not defined:
m4_default

macros defined in autoconf.texi:
dnl
m4_bpatsubst
m4_define
m4_defn
m4_dquote
m4_if
m4_pattern_allow
m4_pattern_forbid
m4_popdef
m4_quote
m4_undefine
