    *) Bugfix: the ngx_http_stub_status_module showed incorrect statistics
       if "rtsig" method was used or if several worker process ran on SMP.

    *) Bugfix: nginx could not be built by the icc compiler on Linux or if
       the zlib-1.2.x library was building from sources.

    *) Bugfix: nginx could not be built on NetBSD 2.0.
