Use unsigned to represent memory flags size

[JetXujing]

Left shift of WORD_SIZE and INT_SIZE by 30 places cannot be represented in type 'int'. Using 'unsigned int' instead.

this should also affect INT_SIZE so wouldn't it be better to approach it instead with at least something like:

Yes, I agree with you and I have made the relevant changes. In addition, the input parameters of some functions and variable types are adjusted to avoid implicit conversion.
