I'm more or less referring to the internals, why is it a constant expression in

the first case, but not treated as an integer constant expression.



Also, according to the rules of indirection (6.5.3.2):

If [a string literal X] has type "pointer to TYPE" then *X should have type X.



Now if internally *" " is a integer (or char) internally, and taking the rules

of indirection literally, then



  enum {foo = *" "};



should be (in my eyes) the same as



  enum {foo = (char)32};
