Re: template specializiation

Thomas,

  Sure.  What version of Visual Studio are you using as I don't know
that I've had to use this in my MSVC development yet.

14.7.3.15

An explicit specialization of a static data member of a template is a
definition if the declaration includes an
initializer; otherwise, it is a declaration. [Note: there is no syntax
for the definition of a static data member
of a template that requires default initialization.
template<> X Q<int>::x;
This is a declaration regardless of whether X can be default
initialized (8.5). ]
