(side note: I have to admit that having configure tell me at the end which GTK+ backend is used was quite convenient on systems like OS X where two different backends of GTK+ are available ;) )
I agree that it would be a useful thing to have, but unfortunately there doesn't seem to be a convenient means of testing for this with Gtk+ 3. I guess it would be possible to put in a loop to check through all known backends.

Configure and make on OS X 10.7.5 for GTK+/Quartz (as well as for GTK+/X11) succeeds with r12250 - thx :-)

@Tavmjong - Your problem occurs because the GTK_CHECK_BACKEND macro is only available when Gtk+ 3 development libraries are installed. I've put a guard for this in r12249
@suv - Your problem occurs because I'm an idiot... equality operators need something on the right hand side! Fix on its way!

r12247 fails to configure on OS X 10.7.5 with GTK+/Quartz 2.24.17 (wrongly detects X11 backend (backend is Quartz), and then fails to find a package 'x11'):
checking if Gtk+ 2.0 is using the X11 backend target... yes checking for X11... no configure: error: Package requirements (x11) were not met:
No package 'x11' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.
Alternatively, you may set the environment variables X11_CFLAGS and X11_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. make: *** [config.status] Error 1

It turns out that we *did* need to explicitly link to -lX11 because we use the X11 library directly (not just as the Gtk+ backend). I've restored the test in r12247 for Gtk+ 2 builds, and added a new test for Gtk+ 3 builds.

OK... done in r12244. The only real disadvantage, I guess, is that we no longer have a handy variable for debugging purposes. However, it's not Gtk+ 3 compatible, so it was only of limited usefulness.
