  MFC r320240:
  
    Use __ISO_C_VISIBLE, as opposed to testing __STDC_VERSION__.
  
    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/.
