When the old style of AC_INIT is used (with a single argument
that indicates a file to check for) recent Autoconf omits
Autoconf version info from the generated configure's --version
output. Using the modern style of AC_INIT fixes the problem.
This is a forwarded copy of a bug reported against Debian's
package for Autoconf, which I maintain. I've included the
original bug report below.

Package: autoconf
Version: 2.59-8
Severity: minor
Should be obvious from this example:
source% autoconf2.13
source% ./configure --version
configure generated by autoconf version 2.13
source% autoconf2.50
source% ./configure --version

source% $EDITOR configure.in
... changing AC_INIT
from: AC_INIT(include/foo.h) <-- old 2.13 syntax
to: AC_INIT(mypackage, 3.3) <-- new syntax
source% autoconf2.50
source% ./configure --version
mypackage configure 3.3
generated by GNU Autoconf 2.59
The configure generated with 2.5x should really say, that
it was generated using 2.59, even for oldish configure.in.
