Import <stdnoreturn.h>
This header conforms to the C11 standard Reference: ISO/IEC 9899:201x 7.23 _Noreturn <stdnoreturn.h> According to ISO/IEC 9899:201x (draft) <stdnoreturn.> defines the noreturn macro which expands to _Noreturn. The _Noreturn keyword appears in a function declaration and specifies that the function does not return by reaching the end of the function body. Design choices: - don't implicitly break C++ code including this header with #error C++11 offers [[noreturn]] which conflicts with C11 _Noreturn - don't check for __STDC_VERSION__, everybody is free to reuse it with a nonstandard compiler not conforming to C11 but supporting _Noreturn gcc(1) and clang(1) support _Noreturn in -std=c99 and older standards this follows <stdbool.h> choice for not checking for C99 - follow <stdbool.h> and declare the __noreturn_is_defined guard - use a standard header guard (_STDNORETURN_H_), similar to <stdbool.h> Reviewed by <pgoyette> and <joerg>
