Version 2.72a fails with libarchive git version

[Werner LEMBERG]

[for completeness I send this bug report to bug-autoconf, too]


[autoconf 6d38e9fa2b]
[clang 9.0.1]
[https://github.com/libarchive/libarchive.git]


Running

  autoreconf -fvim

in libarchive's git repository, then executing

  CC=clang ./configure

fails as below.  I had to use autoconf version 2.69 to create a
`configure` script that could be successfully executed.
