Changeset 17677 for trunk/Mars/mcore/zofits.h

Message:

Fixed the last fix... using a variable type which allows hundreds of terabytes to be allocated is for sure no option. Actually, restricting the amount of memory which can be allocated is a feature not a problem. The correct way to fix the problem is to properly cast the variable before it is converted from kB to Byte.
