+    // GTK+ can reliably detect Meta key state only since 2.10 when
+    // GDK_META_MASK was introduced -- there wasn't any way to detect it
+    // in older versions. wxGTK used GDK_MOD2_MASK for this purpose, but
+    // GDK_MOD2_MASK is documented as:
+    //
+    //     the fifth modifier key (it depends on the modifier mapping of the X
+    //     server which key is interpreted as this modifier)
+    //
+    // In other words, it isn't guaranteed to map to Meta. This is a real
+    // problem: it is common to map NumLock to it (in fact, it's an exception
+    // if the X server _doesn't_ use it for NumLock).  So the old code caused
+    // wxKeyEvent::MetaDown() to always return true as long as NumLock was on
+    // on many systems, which broke all applications using
+    // wxKeyEvent::GetModifiers() to check modifiers state (see e.g.  here:
+    // http://tinyurl.com/56lsk2).
+    //
+    // Because of this, it's better to not detect Meta key state at all than
+    // to detect it incorrectly. Hence the following #define, which causes
+    // m_metaDown to be always set to false.
+    #define GDK_META_MASK 0
