+G++ allows floating-point literals to appear in integral constant expressions,
+e.g. @samp{ enum E @{ e = int(2.2 * 3.7) @} }
+This extension is deprecated and will be removed from a future version.

+G++ allows static data members of const floating-point type to be declared
+with an initializer in a class definition. The standard only allows
+initializers for static members of const integral types and const
+enumeration types so this extension has been deprecated and will be removed
+from a future version.
