Umm, I see. Thank you for clarification.

My previous patch had two problems on alpha:
- sys/alpha/linux/linux.h did not define LINUX_AF_INET6.
- linux_connect() called linux_sa_get(). linux_sa_get() calls
linux_to_bsd_domain(). But, linux_to_bsd_domain() was not
compiled in on alpha.
I believe that these problems were gone in my current patch.
Maybe, you saw new one. :)
Sincerely,
