 * 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.
 *
 * Wed Sep 14 12:34:00 1994 Alessandro Forin (sandrof@microsoft.com)
 *  Reduced for MMLITE use (no MS extensions).
 *  Upgrade to BSD4.4 pending.
