About the best fix I can think of (and it's not very good) is to
change <netinet/in.h> so the structure is declared like this:
struct ip_opts {
struct in_addr ip_dst; /* first hop, 0 w/o src rt */
#ifdef __cplusplus
char ip_optbuf[40]; /* actually variable in size */
#else
char ip_opts[40]; /* actually variable in size */
#endif
};
This shouldn't break any C++ code, since it already wouldn't compile
anyway. :-)
