Then how about simply:
#ifndef STATIC_NDEBUG
# define BOOST_STATIC_ASSERT2(e) BOOST_STATIC_ASSERT(e)
#else
# define BOOST_STATIC_ASSERT2(e) // Possibly "void(0)" here, like
"assert"
#endif
By the way, what's the point with "void(0)", compared to nothing? Both
"void(0);" and ";" are valid statements.
