Both the Standard & MSVC6 allow a (const char*) as a template parameter.
What is rejected (by both) is a text literal parameter. For a non-type
parameter, the value must be a constant across all translation units linked
together, hence it must be defined extern.
template <const char* S> SomeClass { ...};
SomeClass<"YourParam"> NoGood;
extern const char* MyParam = "MyParam";
SomeClass<MyParam> Acceptable;
