+
+ Simplify the handling of `acconfig.h'.
+
+ * autoheader.sh: No longer try to select the needed paragraphs of
+ `acconfig.h', just dump everything into `config.h.in'.
+ Implement support for `--warnings'.
+ Warn the users that these auxiliary files are obsolete when `-W
+ obsolete'.
+ * doc/autoconf.texi (Invoking autoheader): Adjust.
