nginx-0.1.33-RELEASE import

    *) Bugfix: nginx could not be built with the --without-pcre parameter;
       the bug had appeared in 0.1.29.

    *) Bugfix: 3, 4, 7, and 8 the "proxy_set_header" directives in one
       level cause the bus fault on start up.

    *) Bugfix: the HTTP protocol was specified in the HTTPS redirects.

    *) Bugfix: if the "rewrite" directive used the captures inside the "if"
       directive, then the 500 error code was returned.
