Whether something is a constant expression or not is one thing, whether you can
fold a non-constant expression from standards POV into a constant is another
thing.  That folding is optional, it is an optimization, while the standard
requires that enum constants are constant expressions and GCC doesn't include
*" " among valid constant expressions.  No idea why you need it, you can use '
'
which is a valid constant expression.
