correct version of the autoconf tools?

[Thomas Stüfe]

Hi all,

What is the correct version of the autoconf tools to use when regenerating
generated-configure.sh?

I am generating with autoconf 2.69 and get a number of diffs unrelated to
my change, among others:

+  -runstatedir | --runstatedir | --runstatedi | --runstated \
+  | --runstate | --runstat | --runsta | --runst | --runs \

etc. I see option runstatedir has been removed in "8166937: [Solaris]
Missing libjvm_db.so and libjvm_dtrace.so from JDK 9 b138". Was that
delibarate? Am I using the wrong autoconf?

Or, asked another way, should I even care? When providing webrevs for
changes in m4 files, should I also provide an updated configure script? And
if yes, should it only diff minimally?

Thank you!

Thomas
