With automake version 1.13.2 (which comes in debian testing/jessie),
we were starting to get these warnings by default:
...

We simply follow the warning's recommendation of using AM_CPPFLAGS instead
(CPP meaning C PreProcessor, not C Plus Plus), as explained in
http://www.gnu.org/software/automake/manual/html_node/Program-Variables.html
The deprecation of INCLUDES has been very long there already (since 2002,
therefore Automake 1.7), and we already depend on automake 1.10.
This is a mono profiler module that can be used to detect when GTK or
GDK methods are called from a thread which is not the main GUI thread.
Thanks to Andrés Aragoneses for doing the work to bring this into Gtk#.
