Template bug in gcc 2.95 and 2.95.1?

No, it is a bug in your code. "Obj const *" and "const Obj *" is
really the same type; you can freely put cv qualifiers before or after
the innermost type. Following the same pattern,

const char *x;
char const *y;

are the same type as well, don't you agree? "char * const z" would be
differently.

Since they are the same type, you get a duplicate instantiation. Now,
it would look like a bug in Sun CC that they don't report
that. However, I believe duplicate instantiations don't need to be
diagnosed.
