I lied.
They're actually using that stuff to pick apart the (presumed IEEE 754)
doubles into exponent, mantissa, ...
My questions still stand ...
Also, that file is such a tangled nest of ifdefs ...
is anyone sure whether (and if so, when) that code is invoked?
interesting conflicts on the web. http://en.wikipedia.org/wiki/IEEE_754
says c doesn't require ieee, http://home.datacomm.ch/t_wolf/tw/c/c9x_changes.html point #21.
says it does.
in any event, if ieee is used, i think the trick is safe.
