Follow-up Comment #33, bug #40607 (project octave):
>> uint64(2)^63
ans = 9223372036854775808
>> uint64(2)^63-1
ans = 9223372036854775808
>> uint64(2)^63-2
ans = 9223372036854775808
>> int64(2)^63
ans = 9223372036854775807
>> int64(2)^63-1
ans = 9223372036854775807
>>
Cross compiled config.h:
#define SIZEOF_LONG_DOUBLE 12
#define HAVE_ROUNDL 1
A earlier version of octave natively compiled reports the same in config.h
