I do not believe Octave does anything special wrt IEEE 754 beyond what
underlying C++ compiler/library does.
That came up few times and the conclusion was that it is not Octave's business
to fix compiler bugs/missing features.

GCC compliance with IEEE 754 is iffy at the moment. The result may even change
with different optimization level.
