Comment (by ballapete):

 Choosing the second solution the file is compiled and a new error appears:

 {{{
         /usr/bin/gcc-4.2 -DHAVE_CONFIG_H
 -DSYSTEM_WGETRC=\"/opt/local/etc/wgetrc\"
 -DLOCALEDIR=\"/opt/local/share/locale\" -I.  -I../lib -I../lib

 }}}

 Its cause is similar:

 {{{
  1366   static void
  1367   bar_set_params (const char *params)
  1368   {
  1369   /* if run_with_timeout() will be used for read, needs to disable
 interactive bar,
  1370      or  on every timeout(1s) we will have 'retry' with error
 "decryption failed" */
  1371   #if (defined(HAVE_LIBSSL) || defined(HAVE_LIBSSL32)) &&
 defined(OPENSSL_RUN_WITHTIMEOUT)
  1372     current_impl->interactive = false;
  1373   #else
  1374     current_impl->interactive = true;
  1375   #endif
  1376     if (params)
  1377       {
  1378         for (const char *param = params; *param; )
  1379           {
  1380             if (!strncmp (param, "force", 5))
  1381               current_impl_locked = 1;
  1382             else if (!strncmp (param, "noscroll", 8))
  1383               opt.noscroll = true;
  1384
  1385             if (*(param = strchrnul(param, ':')))
  1386               param++;
  1387           }
  1388       }
 }}}

 Here the re-declaration of `param` looks faulty since its type is known
 from the function's definition.
