No, and GCC 4.6 is supporting them. See
http://gcc.gnu.org/projects/cxx0x.html

The macro might be named BOOST_NO_UNRESTRICTED_UNIONS.

See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2544.pdf

Do you have an actual need for such a macro? We only want to add macros that
will be actually used by Boost libraries.

If you do have a need, would you like to try your hand at providing the
macro, test cases, docs, etc?
