Thank you for taking a stab at the documentation.

Not quite.  There are two completely orthogonal extensions: (1) we allow 
floating-point literals in integral constant expressions, and (2) we 
allow in-class initialization of static data members of floating-point type.

An example of (1) without (2) is something like:

  enum E { e = int(2.2 + 3.7) };

which is invalid ISO C++, but is accepted by G++, without -pedantic.

Joseph Myers is probably the right person to ask about that.

I think that you should also move these descriptions under "Deprecated 
Features", as nobody objected to deprecating this extension.
