There is the link command generated by autotools:
gcc -mwin32 -g -O2  -o dp40.dll -shared
-Wl,--export-all-symbols -Wl,-s dpChan.o dpCmds.o
dpRPC.o dpPlugF.o dpFilte
rs.o dpIdentity.o dpPackOff.o dpInit.o dpSerial.o
dpSock.o dpWinInit.o dpWinSerial.o dpWinSock.o
dpWinTcp.o dpWinUD
P.o dpWinIPM.o -ltcl84 -lws2_32

If I omit -lws2_32, I receive "undefined reference"
for winsock functions (one of the source has
#include <ws2tcpip.h> for IP multicast).
What should I do?
