Follow-up Comment #41, bug #40607 (project octave):

ok - found it.

Assuming the change in comment 35:

if I did a make clean; make and then run ./run-octave, uint64(2)^63-1 doesn't
work, and I couldn't seem to make a breakpoint and see what was going on in
gdb.

If I comment out OCTAVE_LONG_DOUBLE_OP (-, sub) and manually add the
equivalent of expanded #define OCTAVE_LONG_DOUBLE_OP, and put a
printf("%Lf\n", retval) in it, it prints out the correct answer AND returns
the correct answer.
