Subject: Explicit typecast of unused constant to make 32 bit compiler happy.

Explicit typecast of unused constant to make 32 bit compiler happy.

Summary:
GCC 5.3 is confused that we might be trying to assign a 64
bit value to a 32 bit size_t although we are clearly not.  Just
typecast the confusion away.
