It shouldn't be a problem for gnulib, as Gnulib uses _Noreturn,
and arranges for _Noreturn to be #defined appropriately
on pre-2.8 GCC and other pre-C11 platforms.

Here's Gnulib's current implementation of that:

#ifndef _Noreturn
# if (3 <= __GNUC__ || (__GNUC__ == 2 && 8 <= __GNUC_MINOR__) \
      || 0x5110 <= __SUNPRO_C)
#  define _Noreturn __attribute__ ((__noreturn__))
# elif 1200 <= _MSC_VER
#  define _Noreturn __declspec (noreturn)
# else
#  define _Noreturn
# endif
#endif
