getaddrinfo needs socklen, sync from coreutils

[Jim Meyering]

I've just discovered/fixed a build problem with the getaddrinfo module.
It didn't depend on the socklen module (for the declaration of socklen_t).
So I've merged these changes from coreutils:

2005-09-23  Jim Meyering  <address@hidden>

        * modules/getaddrinfo (Depends-on): Add socklen.

2005-09-23  Jim Meyering  <address@hidden>

        Sync from coreutils.
        Correct build failure (socklen_t not defined) on at least
        mips-sgi-irix6.5 and alphaev67-dec-osf5.1.
        * getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Require gl_SOCKLEN_T.

2005-09-22  Paul Eggert  <address@hidden>

        Sync from coreutils.
        * getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Check for netinet/in.h.
