LYNX-DEV _WINDOWS patch for doing NSL_FORK

[afn06760]

Code added to WWW/Library/Implementation/HTTCP.c. 
This actually seems to work.  (Sorry, not in patch
format)
=================================================

#ifdef _WINDOWS
void _fork_fun (void *phost)
{
  long r_val;

  r_val = (long)gethostbyname(*(((char ***)phost)[1]));
  if (r_val == (long)NULL) r_val = -1L;
  *((void ***)phost)[0] = (void *)r_val;
}
#endif

====================================================

        FREE(host);
        if (soc_in->sin_addr.s_addr == 0) {
                 if (TRACE)
                          fprintf(stderr,
                         "HTTPAccess: Can't find internet node name 
`%s'.\n",host);
                 return -1;  /* Fail? */
        }
#else
#if defined(_WINDOWS)
        {
         void *arglist[2];
         pid_t fpid;

         arglist[0] = (void *)&phost;
         arglist[1] = (void *)&host;

         phost = (void *)NULL;
         fpid = (pid_t)_beginthread(_fork_fun, 4096, arglist);
         while (!phost)
          if (HTCheckForInterrupt())
           {
            if (!phost) CloseHandle(fpid);
            FREE(host);
            return HT_INTERRUPTED;
           };
         };
         if (phost == ((void *)-1L)) phost = (void *)NULL;
#else
        phost = gethostbyname(host);    /* See netdb.h */
#endif /* _WINDOWS */
#ifdef MVS
        if (TRACE) {
            fprintf(stderr,
                    "HTParseInet: gethostbyname() returned %d\n", phost);
