This uses native support for static assertions if it is available (as is true in gcc with version >= 4.6 or the Microsoft compiler with version > 1600). In this case, the resulting error message should include the message passed to the constructor. If there is no native support, we fall back to a macro defined here that causes a compilation error something like this:

error: size of array 'static_assert_failed_at_lineXXX' is negative

Note

if the macro is used, the expr argument may have to be parenthesized if it contains commas.
