Yes, that's "normal".  The x86 FPU sometimes computes in
"long double" mode internally, and when rounding back
to "double", it's in the wrong rounding mode.  Also,
trig functions often are worse than 1 ulp.

Should be fixed now.  The #include order needed to be adjusted
to complete the <limits> workaround.  It's not pretty and
needs re-thinking.
