      further use of _Noreturn, for non-plain-C functions · 0c05bd3a
      Rich Felker 提交于
      note that POSIX does not specify these functions as _Noreturn, because
      POSIX is aligned with C99, not the new C11 standard. when POSIX is
      eventually updated to C11, it will almost surely give these functions
      the _Noreturn attribute. for now, the actual _Noreturn keyword is not
      used anyway when compiling with a c99 compiler, which is what POSIX
      requires; the GCC __attribute__ is used instead if it's available,
      however.
      
      in a few places, I've added infinite for loops at the end of _Noreturn
      functions to silence compiler warnings. presumably
      __buildin_unreachable could achieve the same thing, but it would only
      work on newer GCCs and would not be portable. the loops should have
      near-zero code size cost anyway.
      
      like the previous _Noreturn commit, this one is based on patches
      contributed by philomath.
