That sounds reasonable. You're right that Posix doesn't require this
"feature", though it allows it. By "making a warning" do you mean
that we just put a warning in NEWS about it, or something more
elaborate?

Are you talking about this change? (If so, I bear part of the blame. :-)

%union directives can now have a tag before the `{', e.g., the
directive `%union foo {...}' now generates the C code
`typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
I just checked with Solaris 10 /usr/ccs/bin/yacc, and it allows
arbitrary C code (not just a single identifier) in that position.
So even if we added the feature for C++ code, there's a compatibility
argument for it as well, and we should probably leave it alone.
