Something like this is OK. But this change drops support for [[noreturn]]
in compilers other than GCC and clang. Shouldn't it be like this:
# if (201103 <= (defined __cplusplus ? __cplusplus : 0) \
&& (!defined __GNUC__ || 4 < __GNUC__ + (8 <= __GNUC_MINOR__)))

The effort to distribute (in a module) and include this file may well
be larger than the gain, no?
Also, in this case the code duplication is between a file in m4/ and
a file in lib/. However, we don't have a good way to share code between
m4/ and lib/, because an include statement in a .m4 file
#include "$srcdir/lib/foo.h"
would need to reference the gnulib-tool --source-base value instead of 'lib'.
