it includes another AU defined macro. * autoupdate.sh (input.m4:_au_defun): New macro. (au.m4): Use it instead of inlining _au_enable/_au_disable invocations in the definition of all these macros. (input.m4:__au_enable, input.m4:__au_disable): New macros. (input.m4:_au_enable, input.m4:_au_disable): Use them. * tests/mktests.sh (update_exclude_list): Add `AC_OUTPUT'. Running it twice in a configure.in is not valid. Add `AC_LINK_FILES' since it requires arguments. * tests/tools.m4 (autoupdating AC_LINK_FILES): New test.
