After the latest gtk updates, master fails to build for me on a
SLES11SP3 machine:

/home/cohuck/git/qemu/ui/gtk.c: In function ‘gd_key_event’:
/home/cohuck/git/qemu/ui/gtk.c:943: error: ‘GDK_KEY_Pause’ undeclared (first use in this function)
/home/cohuck/git/qemu/ui/gtk.c:943: error: (Each undeclared identifier is reported only once
/home/cohuck/git/qemu/ui/gtk.c:943: error: for each function it appears in.)

Of course, the gtk version is not the freshest:

pkg-config --modversion "gtk+-2.0"
2.18.9

On machines with less-ancient gtk (say 2.24) everything builds fine.

I don't really care about gtk support on the SLES11 machine (it's s390
anyway), but we should probably either fence the pause key support or
have configure require a more recent version.

I think I saw the same thing on RHEL 6 (and hacked around it because I
didn't have time to investigate it).

In older versions of GDK, the constants were lacking the 'KEY_' part,
so it would have just been  GDK_Pause.

In GTK-VNC I worked around this by adding this kind of thing to our
source

  #ifndef GDK_Return
  #define GDK_Return GDK_KEY_Return
  #endif

Since there was a fairly small set of key constants that we needed to
care about.

Regards,
Daniel

Indeed ui/gtk.c already has a number of similar workarounds.

Untested fix below. Cornelia or Kevin, can you confirm?

With this change, master builds for me again.

That seems to fix it for me.
