I have read the manual, but my understanding was that the Intel core2 duo processors supported 128 bit width (from the intel core2 instruction set manual: "...and enabling support for 128 bit integers..."). I assumed that the reason long long was showing up as 64 bits instead of 128 was part of the problem that was causing __int128 to not work (perhaps a compiler flag I had missed or something else).
Please don't top-post. Intel core2 duo processors support 128-bit constants, gcc doesn't, at least for this target. Andrew.
