Fix Wundef warning for __STDC_VERSION__
c4c4124473c187b5c4642611390897666c3d3970 added the _Noreturn macro for
pre-C11 compilers, but it now throws a new Wundef warning during `make
check` for __STDC_VERSION__ which gcc does not define by default. The
following patch fixes this in line with other uses of __STDC_VERSION__
in the file.
