Re: Current CVS Fails to Compile on FreeBSD

[Federico Montesino Pouzols]

        I see. It seems that using 

#if defined(IP_ADD_MEMBERSHIP) && defined(SIOCGIFINDEX)

        is enough to make ccpp compilable on FreeBSD again, as
SIOCGIFINDEX is defined if the problematic ip_mreqn structure is
available. It is fixed in CVS.
