FreeBSD's C library uses __STDC_VERSION__ to determine whether the compiler provides language features specific to a certain version of the C standard. __ISO_C_VISIBLE is used to specify which library features need to be exposed. max_align_t currently uses __STDC_VERSION__, even though it should be using __ISO_C_VISIBLE to remain consistent with the rest of the headers in include/.
