Mask_underflow

Has this been implemented in the 64bit version? Our old code gives an error on this, and checking inside salflibc64.dll I cannot find it. Thanks

MASK_UNDERFLOW@() is not implemented in the Silverfrost 64 bit DLLs.

At the moment I don't know if the 64 bit processor has masked and unmasked states for underflow. If it doesn't then there is no reason to set the flag either way.

I suggest that you comment out the call to MASK_UNDERFLOW@() to see if it has any adverse effect. If it causes a problem then you could report back and describe what has gone wrong.
