        * ace/Select_Reactor_T.cpp:

          Added a reset of errno during the ctor in case there was an
          error during the first attempt at opening the reactor. Turns out
          that in this case on at least on Linux, the errno leaks through
          the second, good call to open. This can happen for example, when
          ACE::max_handles() is less than the select reactor's DEFAULT_SIZE.
          Since all this happens in a ctor, there's no result value for
          application code to check, apart from errno.
