Synopsis: Full specialisation of member templates failing

State-Changed-From-To: open->closed
State-Changed-By: lerdsuwa
State-Changed-When: Sun May 19 04:28:49 2002
State-Changed-Why:
    Not a bug.  Explicit specialization of member templates,
    while the enclosing class is not specialized, is not 
    allowed in the C++ standard.  For details, see section
    14.7.3 para 8 of the standard.

>Description:
The attached program tries to specialise a member class
template in (hopefully) all possible ways.  Partial
specialisations succeed, but full specialisation succeeds
only when the enclosing class is non-templated, and the
specialisation is declared outside of the enclosing class.
