How does one make the distinction (in C, as proposed by ANSI) between "a
volatile pointer to something" and "a pointer to volatile something"?  An
example of a pointer to a volatile is the address of a memory-mapped
device register; an example of a volatile pointer is an extern referenced
in a signal handler.  I imagine it is also possible to have a volatile
pointer to a volatile something, but I can't think of any worthwhile
examples.
