I think you confused Michael. ;)

At the moment you can define external const like this:
var
  NaN: Double; external name 'NaN';
  Infinity: Double; external name 'Infinity';
  NegInfinity: Double; external name '-Infinity';

Note that the 'var' is a workaround till eventually pas2js supports
external 'const' without expression.

A const inside an external class already works:

type
  TMyExt = class external name 'Bla'
    const LoVersion: GLFloat;
    const HiVersion: GLFloat; external name 'hiversion';
  end;
