data types and associated sizes

[ghost]

Hello,

In the file aes.c, line 67, the 32 bits unsigned integers are defined as follows :
typedef unsigned long uint_32t;

On a 64 bits machine, this data type is expanded to a 64 bits integer.
May I suggest you to use the stdint.h header and use the uint32_t data type for portability sake ? For debugging purpose, it would be useful to avoid cross compiling every time.
