Browse Source 
../../../../src/../test/unit/ip4/test_ip4.c: In function ‘test_ip4_icmp_replylen_short’:
../../../../src/../test/unit/ip4/test_ip4.c:291:35: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
   fail_unless(linkoutput_byte_ctr == icmp_len + sizeof(unknown_proto));

Plus minor cleanup in second icmp reply test
