+ _Noreturn: future-proof non-GNU and non-MSVC compilers

+ * m4/gnulib-common.m4 (gl_COMMON_BODY):
+ Do not define _Noreturn if __STDC_VERSION__ indicates this is
+ C11 or later. This is more likely to work with random future C
+ compilers that are neither GNUish nor MSVCish. See Vincent Lefevre in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2012-04/msg00195.html>.
