[Bug c++/20547] undefined reference to "static const" fields of classes

["Hu dot YuehWei at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

so the "... = 3;" initialization statement below is a definition or a declaration?
According to the C++ standard, its a definition.
Should the compiler allocate a memory space for it?

struct T
{
  static char const a = 3;
};

And...
If I need to allocate memory spaces for it manually, why the standard explicitly
specify this kind of coding style?
========================
struct T
{
  static char const a = 3; /* standard explicity specify that the initialization
& definition can be put here. */
};

char const T::a; /* If I need this line of codes, then the initialization above
should be a declaration, not a definition. But a declaration can be initialized? */
========================
struct T
{
  static char const a;
};

char const T::a = 3;
========================
