[Moderator's note: This is crossposted to comp.std.c++ and

I recently came across a piece of code that reads:

class A {
  // contents of class A
} a1, *a2, const *a3;


This looks pretty bogus to me.  I thought that the 'const' applied
to the elaborated specifier 'class A'.  If the 'const' qualifier is
supposed to apply to the pointer in 'a3', then it should come _after_
the '*'.

I think that either one of the two following was intended.

1)

class A {
  // contents of class A
} a1, *a2, * const a3;


2)

class A {
  // contents of class A
} a1, *a2;

A const *a3;  // Or const A *a3;


Is my interpretation of the binding of 'const' more or less correct?

BTW, this code _is_ accepted by the Microsoft VC/C++ v2.0 compiler.
