bug#7484: 24.0.50; Network functions from process.c aren't built anymore

[Tassilo Horn]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

At least 2 network functions defined in process.c are not built anymore.
This regression is at most a few days old.

The functions that are missing in my compiled Emacs are

  network-interface-list
  network-interface-info

They are wrapped in

#if defined(HAVE_NET_IF_H) && defined(HAVE_SYS_IOCTL_H)

and the former also in

#ifdef SIOCGIFCONF

Because both are missing, it seems HAVE_NET_IF_H or HAVE_SYS_IOCTL_H is
not defined when compiling.  But I do have both

  /usr/include/net/if.h
  /usr/include/sys/ioctl.h

So something seems to be wrong with configure...

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.0.50/etc/DEBUG.
