The problem
-----------

In the repository, the definition for ``AX_CHECK_COMPILE_FLAG`` in Python's ``configure.ac`` file is missing. If ``autoreconf`` is run, an invalid ``configure`` script is generated. The following is the behaviour of running ``autoreconf`` followed by ``configure``:

```
# In cpython repository top-level directory
$ autoreconf
$ mkdir build
$ cd build
$ ../configure  # <- using newly generated configure script
[... omitted ...]
checking for --enable-optimizations... no
../configure: line 6498: syntax error near unexpected token `-fno-semantic-interposition,'
../configure: line 6498: `      AX_CHECK_COMPILE_FLAG(-fno-semantic-interposition,'
```


The solution
------------

It appears a file was missing in the m4/ directory. The file matches this one from the Autoconf Archive:

https://www.gnu.org/software/autoconf-archive/ax_check_compile_flag.html

Simply adding the correct m4 file to m4/ should make ``autoreconf`` work.
