うーーん、ここでやりたかったのは、

<<AC_OBJEXT のオーバーロード>>
    もし、AC_OBJEXT が未定義ならば
	AC_OBJEXT を
	    OBJEXT に o を代入する 
	と定義する
    もしくは
	AC_OBJEXT に OLD_AC_OBJEXT なる別名をつけ
	AC_OBJEXT を
	    もし human68k なら OBJEXT に o を代入する
	    もしくは  OLD_AC_OBJEXT をよび出す
        と再定義する
    おわり

という処理なんですが、 autoconf は define を直接呼ばず、
AC_DEFINE というマクロでくるんでいるくらいなので、
  『m4 の defn を直接つかったらきっとヤバイ』
と思ったわけです。
＃ AC_IFDEF, AC_DEFN や AC_UNDEFINE は無かったです。^^;;;;

ifdef とか pushdef/popdef とかがあるので、きっとできると
思うのですが、autoconf の実装の内部を理解する必要があるので、
挫折しました。

このへんが
  autoconf-2.13 以降の機能を含んだ configure.in から
  autoconf-2.12 以前を使って configure を生成するために、
  aclocal.m4 を細工してなんとかしよう
という発想の限界かも知れません。
