Issue #13946 has been updated by kernigh (George Koehler).


I had an old Makefile before I pulled this change (rename configure.in to configure.ac). The old Makefile can't find configure.in. The fix is easy: run autoconf and ./configure to get a new Makefile.

The error from an old Makefile looks like:

```
$ make
...
make: don't know how to make ../ruby/configure.in (prerequisite of: ../ruby/configure)
Stop in /home/kernigh/park/ruby-build
```

Hello ruby team!

In my quest to learn about Ruby-lang's src i was reading through [autoconf's documentation](http://www.gnu.org/software/autoconf/manual/autoconf.html) and got a bit confused about where the autoconf script was for ruby trunk until i found this paragraph in chapter 3.1:

> Previous versions of Autoconf promoted the name configure.in, which is somewhat ambiguous (the tool needed to process this file is not described by its extension), and introduces a slight confusion with config.h.in and so on (for which ‘.in’ means “to be processed by configure”). Using configure.ac is now preferred. 

trunk is currently using `configure.in` - so i would like to propose we rename `configure.in` to be the preferred `configure.ac`. I think this is good and will help reduce confusion for anyone reading documentation for autoconf.

Thank you!
