Changes with nginx 0.5.11 05 Feb 2007

    *) Feature: now configure detects system PCRE library in MacPorts.
       Thanks to Chris McGrath.

    *) Bugfix: the response was incorrect if several ranges were requested;
       bug appeared in 0.5.6.

    *) Bugfix: the "create_full_put_path" directive could not create the
       intermediate directories if no "dav_access" directive was set.
       Thanks to Evan Miller.

    *) Bugfix: the "0" response code might be logged in the access_log
       instead of the "400" and "408" error codes.

    *) Bugfix: a segmentation fault might occur in worker process if nginx
       was built with -O2 optimization.
