I guess that ';' would work in most cases. I can't think of a case where it
wouldn't, although it can give warnings on some compilers (try closing a
namespace with curly-brace-semi-colon on some compilers).

Alternatively, we could use::

> #ifndef STATIC_NDEBUG
> #    define BOOST_STATIC_ASSERT2(e) BOOST_STATIC_ASSERT(e)
> #else
> #    define BOOST_STATIC_ASSERT2(e) BOOST_STATIC_ASSERT(true)
> #endif

I'm wondering why we want to make this a 2nd static_assert at all. It seems
to me that once we acknowledge that a compile-time program 'runs' at compile
time, we have a compile time 'debug' and 'release' mode with the
accompanying debug and release versions of the compile time assert. I would
like to see the primary STATIC_ASSERT defined this way, but that's just me
of course :).
