Presumably, the problem is the difference in precision. But what is
"run_C99.bat"? And what platform do you use?
With current GCC 4.8 branch (x86_64-linux) I get the following result:
$ /opt/gcc-4.8-latest/bin/gcc -std=c99 -lquadmath -lm ./test.c -o test_c99 &&
./test_c99

It is possible that the problem is specific to 4.8.1, but I don't have it
installed right now. If someone has, could you check it please.
