Microsoft VC++ won't compile class C { static const int I=1; }.

Browse Source 
Putting initialization into .cc will reduce compiler's abilities
to optimize this constant away.
Defines are not OK as they bloat global namespace.
Looking for a way to declare an efficient named constant in reduced
namespace (i. e. in  a class).
Let's try enums: normally they should be implicitly casted to int.
Let's see if we really have a compiler which won't do that.
