[section Header <boost/core/static_assert.hpp>]

The header `<boost/core/static_assert.hpp>` defines
the macro `BOOST_CORE_STATIC_ASSERT(expr)`, which
expands to `static_assert(expr, #expr)` under C++11
or later, or to a suitable emulation under C++03.

The same functionality is provided by `BOOST_STATIC_ASSERT`
defined in `<boost/static_assert.hpp>`, and the macro
is duplicated here for libraries that already depend
on Core and would like to remove the dependency on
StaticAssert.

[section Synopsis]

``
#define BOOST_CORE_STATIC_ASSERT(expr) static_assert(expr, #expr)
``

[section Example]

```
#include <boost/core/static_assert.hpp>

BOOST_CORE_STATIC_ASSERT( sizeof(char[1]) == 1 );

struct X
{
    BOOST_CORE_STATIC_ASSERT( sizeof(char[2]) == 2 );
};

int main()
{
    BOOST_CORE_STATIC_ASSERT( sizeof(char[3]) == 3 );
}
```
