Would you mind telling the ISO about this observation of yours, so
that the language definition can be adapted to your views? They erronously
claim the identifiers of functions defined in the library clause as
reserved words for identifiers with external linkage.

No, since memcpy is not listed as an identifier with file scope. Only
for identifiers with file scope that do _not_ have external linkage
the reservation is limited to compilation units that include one of
the associated headers.

 Even if I do link with a library which
>defines memcpy, my definition overrides it.

No, the behaviour of such a program is undefined. I see no other possible
interpretation of "If the program declares or defines an identifier with
the same name as an identifier reserved in that context (*) the behaviour
is undefined.

(*) denotes a cross reference that says: Provided that a library function
can be declared without reference to any type defined in a header, it is
also permissible to declare the function, either explicitly or implicitly, 
and use it without including its associated header. 

  I'm not sure how you can
>construe this to mean that 'memcpy' is in any way "reserved".

I'm not sure how you can think that it is not reserved after reading this
thread. The question is whether it is reserved in a freestanding environment,
and the answer from the language definition is "no, it is not", as far as
I understand the language definition. In a hosted environment, it is
reserved through rather explicit verbiage in the language definition,
and the behaviour of programs using reserved identifiers in a context
in which they are reserved, is _explicitly declared undefined.
