nginx 0.5.11
*) 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.
