While older versions of gcc usually had -O0 implying -ffloat-store, the latter
is more likely to accomplish this in recent versions.

>sizeof(long double) gives 12

but 2 of the bytes are left vacant, for convenience of alignment, so they do
nothing for precision or range.  The values in <float.h> are more likely to
express the precision available.
