It was 

process.c: In function `conv_sockaddr_to_lisp':
process.c:2245: dereferencing pointer to incomplete type
process.c:2246: dereferencing pointer to incomplete type
process.c:2249: dereferencing pointer to incomplete type
process.c:2249: dereferencing pointer to incomplete type
process.c:2249: dereferencing pointer to incomplete type
<etc>

The source code in process.c looks like this:
#ifdef AF_INET6
    case AF_INET6:
      {
        struct sockaddr_in6 *sin6 = (struct sockaddr_in6 *) sa;
        uint16_t *ip6 = (uint16_t *)&sin6->sin6_addr;      <======= L2245

All of these places were within #ifdef AF_INET6 regions.  This symbol is
defined in socket.h, and "ls -lu" indicates that my Emacs compiled with
the socket.h in a linux-2.4.17 tree.  It seems that that this socket.h
and Emacs have different ideas about the type sockaddr_in6.  I worked
around this problem by putting #undef AF_INET6 near the top of the file.

Emacs then built immediately! (well, actually, it took nearer 3 hours,
but it managed without further intervention from me.  :-).

However, when I started it up, it complained about this form in my
site-start.el:

    (define-key help-mode-map "\M-n" 'clone-buffer)

I had to wrap this form in an (eval-after-load "help-mode" ....).  Is
this failure to load help-mode at start-up deliberate, or is it a bug?
It used to be loaded, at least as recently as last September.
