bug#7643: Build failure for SGI IRIX MIPS

[Glenn Morris]

I am afraid that without more input from you or someone else using IRIX
who can reproduce this, nothing can be done.

At a guess, maybe you need to compile with -DINET6, in which case a
patch like the following might fix it. But I don't see the point in
installing this without any testing.

If you can reply with the contents of netinet/in.h on your system, that
might help, and we can reopen this if needed.
