Relevant snippet of the offending header file:

----(cut here)----
/*
 * struct used to identify virtual mac addresses. This are
 * created by the ARP code and will be used to identify non
 * default mac addresses. The list will be hashed to allow
 * for faster searches.
 * NOTE: that the flags field must be at the correct offset
 *       since this and the ifnet struct should be interchangable
 *       till a user can determin that this entry is a vmac ifnet
 */
struct vmac_ifnet {
        struct  vmac_ifnet *vmif_next;  /* the next structure in the list */
        char    *vmif_name;             /* name, e.g. ``en'' or ``lo'' */
        char    *vmif_version;          /* The version string.             */
        struct  sockaddr vmif_hwaddr;   /* address of interface */
        int     vmif_flags;             /* up/down, broadcast, etc. */
        int     vmif_refcnt;            /* last one out needs to delete this */
        struct  ifnet *vmif_ifnet;      /* point to the correct ifnet struct */
        struct  sockaddr vmif_paddr     /* protocol address */
};

Note the missing semicolon.

I was able to work around this by placing an edited if.h with other fixed
headers in gcc-3.4.0/gcc/include/root/usr/sys/include/net/.
