Comment (by akimd):

 Wow.  If this test does not pass, it actually means that the main test
 suite is certainly not passing either.  Bison comes with "two" test
 suites: that of the examples (less than a dozen cases), and then the real
 one (more than 700 cases).  It appears you are stuck in the first,
 auxiliary, test suite.  I guess we will need more exchanges after this
 one...

 Your failure shows that your GCC does not grok _Noreturn the way we expect
 it.  Please run `/usr/bin/gcc-4.2 -std=gnu99 -pipe -Os -arch ppc -E
 bison.c` on the attached `bison.c` file and post the output.  For some
 reason we think it supports _Noreturn, but does not, and we need to tune
 the detection to fix that.
