Problem with TCP Option 0x00000008

i have a problem with a program that uses a network license manager.
I've installed native DCOM using the winetricks script. When i start
the program i got the message "fixme:winsock:WS_setsockopt Unknown
IPPROTO_TCP optname 0x00000008" after the loading of native

To work around this i've compiled a modified wine 0.9.44 with an empty
case statement for 0x00000008 in socket.c. It doesn't help much, the
program just fails a bit later.

The TCP Option 0x00000008 is defined as TCP_ATMARK in ws2_ipdef.h in
the Windows SDK. Does anyone know how this should be mapped ?
