Building examples fails

[Nils Caspar <ncaspar me com>]

I'm trying to build the example file `examples/C/glib/list-connections-libnm-glib.c` with the command given 
in the comment:

```
 * Compile with:
 *   gcc -Wall `pkg-config --libs --cflags glib-2.0 dbus-glib-1 libnm-util libnm-glib` 
list-connections-libnm-glib.c -o list-connections-libnm-glib
```

This fails on my Ubuntu 12.04 machine with the following error:

```

Am I missing something? Is the build command still up-to-date?
