[python-committers] autoconf 2.70

[Xavier de Gaye]

It seems that the configure file on the default branch has been generated with
autoconf 2.70. Autoconf 2.70 has not yet been released [1].  The differences
between the generated configure files with 2.69 and 2.70 are a few lines [3]
added by 2.70 with 'runstatedir' in them.  The last old discussion on the
usage of different autoconf versions [2] does not really answer the following
question:

I am using 2.69, should a commit that changes configure.ac respects the
existing 'runstatedir' lines added by a previous commit or uses directly the
configure file generated by 2.69 ?
