New submission from jared jennings <jared.jennings.ctr at eglin.af.mil>:

If the Intel 9.1 compilers are used to compile Python 2.6, the following
compiler error results:

error: identifier "__int128_t" is undefined
    __int128_t sse[MAX_SSE_REGS];

Forum thread regarding lack of support for __int128_t in icc:

Intel C++ Compiler 10.1 for Linux, Intrinsic Reference:

The Intrinsic Reference details (pp. 2-4) the __m128 type supported by
the Intel compiler, and restrictions on its use. (Note that the compiler
used was 9.1 but the documentation is from 10.1.)
