That's a shame, cause it would be useful.

Such a thing does not exist; I don't know if it ever did.  There is a
thing called a transparent union, which is different from c++ anonymous
unions.

I have somewhere a half-done patch for this feature, done with
__attribute__((anonymous)) attached to structures and unions,
but it certainly isn't in the compiler.
