The SGI C compiler treats the following two pointers as unequal:
	register volatile struct foo *p1;
	volatile register struct foo *p2;
p1 is a pointer (in a register) to a volatile struct foo, while
p2 is a volatile pointer (in a register) to a struct foo.

Gcc treats the pointers as identical, and in my opinion this is
as it should be. However, I haven't been able to find anything in
the standard about the interaction of storage classes and type
qualifiers. Since the 'register' in the declaration of p2 already
refers to the variable p2 it is argueable that the volatile in front
of it can't refer to the structure anymore.

Could anyone who knows the standard better than I do please shed
some light on this?

(preferrably by mail, I don't read this group too often. I'll summarize)
