** Changed macros:
* Many macros renamed systematically, but old names are accepted for
backward compatibility.
-* AC_OUTPUT adds the "automatically generated" comment after "#!" lines,
- not before them.
+* AC_OUTPUT adds the "automatically generated" comment only where it
+ find @configure_input@ in an input file, to support files with
+ various comment syntaxes.
* AC_OUTPUT does not replace "prefix" and "exec_prefix" in generated
files when they are not enclosed in @ signs.
* AC_OUTPUT allows the optional environment variable CONFIG_STATUS to
divert(-1)dnl Throw away output until AC_INIT is called.
