make int64 ops implemented with long double work again (bug #40607) * oct-conf-post.in.h : Use SIZEOF_LONG_DOUBLE < 16 in condition used to define OCTAVE_ENSURE_LONG_DOUBLE_OPERATIONS_ARE_NOT_TRUNCATED. * oct-inttypes.h, oct-inttypes.cc: Return octave_int64 or octave_uint64 from external long double operation functions instead of returning long double.
