I found the following behavior while investigating a failing test in quadgk.

a < b should return false, and it does on Linux, but something is wrong
with the MinGW system.  This looks unpleasant to solve.  I filed a report
about it on Savannah (https://savannah.gnu.org/bugs/index.php?40560).

I knew this rang a bell to me, though in the MSVC context. Here's the link:

I'm not saying the problem is identical, but  just tried in my MSVC-compiled octave-3.7.7 and I get the same result as above. Tomorrow, I'll recompile with -fp:strict compile flag (I used to do that in my own compilation scripts, before I switched to MXE).
