Hi
Thanks for your remainder, i think i miss re-running autogen.sh and
configure.
Yes, i am developing against something other than the current trunk,
because what am i developing is not common feature for
all wireshark users, i think. it is kind of self-defined feature for
analyzing whether is there some sctp data chunks with non-continuous
TSN in target pcap file.
