That option is no longer supported.  See
http://xapian.org/docs/deprecation - it's --enable-log you want now.
You should get a warning about passing an unknown option to configure
(though it's the first line output, so gets scrolled off the screen
quite soon):

$ ./configure --enable-debug-verbose
configure: WARNING: unrecognized options: --enable-debug-verbose
[...]

I don't see conflicting information.  The most recent NEWS entry about this
option documents its removal (in 1.1.0):

* configure: --enable-debug and --enable-debug-verbose have been deprecated
  since 1.0.0, so remove specific errors pointing to the replacements.

Older NEWS entries may not be correct for newer releases, but that's
because the NEWS file documents incremental changes in each release.

Just an indication that the server got EOF on the socket (which happens
when the client closes the connection).
