  /* The _Noreturn keyword of C11.
     Do not use [[noreturn]], because with it the syntax
       extern _Noreturn void func (...);
     would not be valid; such a declaration would be valid only with 'extern'
     and '_Noreturn' swapped, or without the 'extern' keyword.  However, some
     AIX system header files and several gnulib header files use precisely
     this syntax with 'extern'.  So even though C23 deprecates _Noreturn,
     it is currently more portable to prefer it to [[noreturn]].
  
     Also, do not try to work around LLVM bug 59792 (clang 15 or earlier).
     This rare bug can be worked around by compiling with 'clang -D_Noreturn=',
     though the workaround may generate many false-alarm warnings.  */
