I've finally gotten hold of a gcc (5.1.0) that produces the unwanted code.

For a *different* test case, even the -O0 and -O2 results differ, since
with -O2 gcc uses mpfr (I think!) for constant folding, which produces
the correct result.


Using -mfpmath=sse seems to fix all test cases that I've tried.
