Subject: [PATCH nfs-utils] Update autoconfig files to work with v2.71
Date:   Tue, 24 May 2022 12:00:56 +1000
Message-id: <165335765658.22265.136811943333028416@noble.neil.brown.name>
Precedence: bulk


OpenSUSE recently updated autoconf to v2.71, and nfs-utils now doesn't
build.  This patch fixes it.  It was mostly achieved with the autoupdate
program.

I haven't updated the AC_PREREQ(), but nor have I confirmed that it
still works with v2.59.  It does seem to work with 2.69.
