This informs the compiler that no code following an assertion failure will execute (unless NDEBUG is defined), which increases the accuracy of compiler warnings and static analyses. For assert.h, put DECLSPEC_NORETURN before the return type in the function declaration to remain consistent with other MSVCRT function declarations.
