     mod_ssl: Fix possible crash on printing CRL details when
     debugging is enabled, if configured to use a CRL from
     a malicious source.  PR 35081.  [Marc Stern <mstern csc.com>]

     <AuthnProviderAlias baseProvider Alias>
     Authentication directives contained within this block can be
     referenced as a new authProvider using the AuthBasicProvider or

     [Brad Nicholes]

     PR 34834. [Timo Viipuri <viipuri dlc.fi>]

     can result in a major performance improvement when the files are

     UserDir directive is present in the config file.
     [Joshua Slive]

     many features and many directives that are at their default
     setting.  Add a selection of example config excerpts for adding
     extra features in the conf/extra/ directory.  Install the
     distributed config and the extra config examples in the
     conf/original/ directory during make install.
     [Joshua Slive, Justin Erenkrantz]

  *) NetWare: Reposition mod_asis, mod_actions, mod_cgi, mod_imagemap,
     mod_userdir and mod_autoindex as shared modules rather than 
     built-in modules within the NetWare build.
     [Brad Nicholes]
