* Change log:
*
* Fri Apr 23 16:31:01 1993 Mark Towfiq (towfiq@Microdyne.COM)
* New version from David Treadwell which adds extern "C" around
* __WSAFDIsSet() and removes "const" from buf param of
* WSAAsyncGetHostByAddr(). Added change log.
*
* Sat May 15 10:55:00 1993 David Treadwell (davidtr@microsoft.com)
* Fix the IN_CLASSC macro to account for class-D multicasts.
* Add AF_IPX == AF_NS.
*
* Tue Oct 19 13:05:02 1993 Mark Towfiq (Mark.Towfiq@Sun.COM)
* New version from David Treadwell which changes type of counter in
* fd_set to u_int instead of u_short, so that it is correctly
* promoted in Winsdows NT and other 32-bit environments.
