Follow-up Comment #34, bug #40607 (project octave):

OK, can you try changing the condition that sets
OCTAVE_ENSURE_LONG_DOUBLE_OPERATIONS_ARE_NOT_TRUNCATED in oct-conf-post.in.h
from "SIZEOF_LONG_DOUBLE == 10" to "SIZEOF_LONG_DOUBLE < 16"?

I'm really not sure what the proper test should be.  We want to catch systems
that might stupidly round to 53-bits precision even when explicitly performing
operations on long double values.
