Newer C++ compilers consider more and more things in EPICS errors. And
maybe they are right.

The problem is
     T  * volatile * buffer;
in epicsRingPointer.h.

I am not sure if "volatile" really makes any sense here.

The other possibility is to cast away the "void" in the destructor.

delete [ ] (T*) buffer;

delete [ ] (T**) buffer;

Or whatever the nicer C++ syntax is (probably using const_cast<T*>()?)

If anyone can suggest us the solution to overcome this error it will be
of help to us.
