In c++ "const T obj;" is a definition (with internal linkage) while in
c it is only a tentative definition (with external linkage).
Moreover, in c++ const data *must* be initialized, either by an
explicitly declared constructor or an initializer.  So in c++ "const
TValue obj;" is indeed an error since TValue declares no constructor
(obviously) and the definition of obj does not specify an initializer,
such as ={}.
