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.

Nelson H. F. Beebe reports a build failure of the 23.2.92 pretest on SGI
IRIX MIPS.

The last Emacs version to build ok was 21.3 in January 2004, so this
appears to be a long-standing bug.
