Those versions don't fully support __int128_t. Cc: qemu-sta...@nongnu.org Signed-off-by: Stefan Weil <s...@weilnetz.de> ---
See http://stackoverflow.com/questions/16447808/bug-with-int128-t-in-clang for more details. Debian wheezy uses clang 3.0 and shows this bug. I did not test whether the QEMU code will work nevertheless, but I think it's better to be on the safe side and disable __int128_t for old clang versions.
