[Voted into WP at October 2003 meeting.]
11.4.5 [class.ctor] paragraph 10 states
A copy constructor for a class X is a constructor with a first parameter of type X & or of type const X &. [Note: see 11.4.5.3 [class.copy.ctor] for more information on copy constructors.]
No mention is made of constructors with first parameters of types volatile X & or const volatile X &. This statement seems to be in contradiction with 11.4.5.3 [class.copy.ctor] paragraph 2 which states
A non-template constructor for class X is a copy constructor if its first parameter is of type X &, const X &, volatile X & or const volatile X &, ...
11.4.5.3 [class.copy.ctor] paragraph 5 also mentions the volatile versions of the copy constructor, and the comparable paragraphs for copy assignment (11.4.5.3 [class.copy.ctor] paragraphs 9 and 10) all allow volatile versions, so it seems that 11.4.5 [class.ctor] is at fault.
Proposed resolution (October 2002):
Change 11.4.5 [class.ctor] paragraph 10 from
A copy constructor for a class X is a constructor with a first parameter of type X& or of type const X&. [Note: see 11.4.5.3 [class.copy.ctor] for more information on copy constructors. ]to (note that the dropping of italics is intentional):
A copy constructor (11.4.5.3 [class.copy.ctor]) is used to copy objects of class type.
