Such an array has no storage associated with its name "foo". Conversely, "extern *foo;" does have such storage. This causes a problem for the routine using "extern *foo;" since the compiler tries to use the symbol "foo" as a storage location with which to point to the array. This problem doesn't occur once the array is passed to a subroutine, since then it is on the stack and therefore references to the array name do pertain to a storage location. It also won't occur if you use "extern foo[];", because the compiler generates different code for accessing "foo" in that case.

This is the only case I am aware of that *foo is different then foo[]; -------
