No, because it is syntactically not a part of the type, as evidenced by the 
int *x, y; example that others have already pointed out. Semantically, it 
is, but the semantics are only computed after doing the syntactic parsing, 
so the whitespace should preferentially match the syntax.

And I consider the idea of banning comma declarations to work around this 
issue to be nothing more than a workaround for poor notation not matching 
the syntax of the language.

int* x; is just as misleading use of whitespace as:
if (foo)
(indented this way and without braces).
