       docs/conf/httpd-std.conf.in: r1.35
       docs/conf/httpd-win.conf: r1.81

     * Fix a problem that caused httpd to be linked with incorrect flags
       on some platforms when mod_so was enabled by default, breaking
       DSOs on AIX.  PR 19012
       This was new breakage with 2.0.45 that has bit at least a
       handful of vocal people, but there is an easy work-around
       (explicitly add --enable-so).

     * Fix ap_construct_url() so that it surrounds IPv6 literal address

       "require" directives, instead of literal spaces only. PR 17135.
