‘analyzer::tcp::SCORE\*  
analyzer::tcp::TCPRS\_Endpoint::scoreRetransmission(analyzer::tcp::SequenceRange\*,  
analyzer::tcp::Segment\*, analyzer::tcp::RETRANSMISSION\_REASON\_CODE,  
HashKey\*)’:  
/home/aramis/bro/aux/plugins/tcprs/src/TCPRS\_Endpoint.cc:1180:47:  
error: call of overloaded ‘abs(unsigned int)’ is ambiguous

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;^
