I think "__m128" would better be treated as plain data type like int and long.
So I prefer the result of "3.5.0 20040626" in comment #2.

Although I have not tested, I guess GCC 3.4.1 on cygwin will also give the wrong
result, whether "__m128" is treated as POD or not. So if we want to fix it on
cygwin, we'd better retarget it at GCC 3.4.2.
