Synopsis: g++ 3.0 has problems with static const int as templated argument

State-Changed-From-To: open->closed
State-Changed-By: aoliva
State-Changed-When: Fri Aug 10 13:11:55 2001
State-Changed-Why:
    Not a bug.  Every static data member must be defined outside the class body if it is referenced in the program, even if it is a const data member initialized with a constant expression inside the class body.  In this case, the definition outside the class body must not contain an initializer.

>Description:
When a static const int is used as a parameter to
any method that takes a template argument, we
get an undefined reference error when linking.

g++-2.95 handles this with no problems.
>How-To-Repeat:
uncomment line 36 or 41
>Fix:
don't know.

Workaround shown in lines 37&38, i.e. make copy of
static const int and then pass copy into method.
