Description: The fix of the loss problem of the last 2 bytes of mantissa on sleipnir has not been successful. It happens when converting from unsigned long long to long double. The failure has been on and off. Solution: Hard set a macro to disable unsigned long long->long double for FreeBSD until a good solution is found to solve this elusive problem. Platforms tested: sleipnir and fuss. Only sleipnir is concerned. Misc. update:
