Problem compiling with SSE intrinsics and -O3

Please post the output of gcc -v.
In fact, I guess it has little to do with Cygwin, as it looks very
much like a gcc bug,
perhaps fixed in a later version of gcc.
Showing that this is a Cygwin bug would need a check that the same
does not happen
on the same version of gcc on Linux, say.
