Dear all, I have now a complete list of changes (attached as diff files). I also changed the handling in socket.[ch]: Instead of using HAVE_SCTP_RECVMSG and HAVE_SCTP_SENDMSG I'm only using HAVE_SCTPLIB. I checked Linux, FreeBSD and Solaris and all have both functions defined in libsctp. Please let me know if it is possible to include these changes in the 1.6.5 release. Best regards Michael PS.: The changes have been tested on FC2 Linux and BSD.
