title: Does GCC have a built-in compile time assert?
body: <p>Our existing compile-time assert implementation is based on negative array index, and it provides poor diagnostic output on GCC. C++0x's <code>static_assert</code> is a very nice feature, and the diagnostic output it provides is much better. I know GCC has already implemented some C++0x features. Does anyone know if <code>static_assert</code> is among them and if it is then since what GCC version?</p>
