Done (that was easy).

Ok, but have not applied that yet, because that is not the end
of it anyway.

This is somewhat more tricky, as it seems that setsockopt() in minix is
far from complete, so lots of #defines are missing from the headers.

You could try (just for the sake of testing compilation) to change the
relevant lines to something like this:

int opt_dontroute(lua_State *L, p_socket ps)
{
#ifdef SO_DONTROUTE
     return opt_setboolean(L, ps, SOL_SOCKET, SO_DONTROUTE); /* 62 */
#else
     return 0;
#endif
}


Then, if luasocket/src/options.c is the last of the problems, we can do 
a better fix later.

Best wishes,
