An static_assert is a keyword that can be used, depending on the standard used:

static_assert in the C++98 standard

static_assert is not supported in C++98:


int main()

{

  static_assert(1==2,"One is not equal to two"); //Fails in C++98

}

Compiler output:


/MyFolder/main.cpp:3: warning: identifier 'static_assert' will become a keyword in C++0x

/MyFolder/main.cpp:: In function 'int main()':

/MyFolder/main.cpp:3: error: 'static_assert' was not declared in this scope

BOOST_STATIC_ASSERT does already allow for compile-time assertions in C++98.
