Details:

There is a minor error in one debug string in sockets.c.

Lines 897 and 898 read:

  LWIP_DEBUGF(SOCKETS_DEBUG, ("lwip_sendto(%d, data=%p, short_size=%d"U16_F",
flags=0x%x to=",
              s, data, short_size, flags));

The 'short_size=%d"U16_F"' part has an extraneous 'd' after the '%', which
will result in this field being printed using the format specifier %d followed
by the literal text of the platform specific U16_F macro.

Assuming none of the other format specifiers need to use platform-specific
macros, the correct version should be:

  LWIP_DEBUGF(SOCKETS_DEBUG, ("lwip_sendto(%d, data=%p, short_size=%"U16_F",
flags=0x%x to=",
              s, data, short_size, flags));
