Follow-up Comment #2, patch #5067 (project lwip):

Isn't this one already applied? I have another patch, though:

Currently, signed and unsigned are compared after the &&:
  (-(err) >= 0 && -(err) < ERR_TO_ERRNO_TABLE_SIZE ? \

since we know err is negative, casting -err to u8_t can do no harm and gets
rid of the warning:
  (-(err) >= 0 && (u8_t)(-(err)) < ERR_TO_ERRNO_TABLE_SIZE ? \
