Ben,
The purpose of the stdint.h file is to allow the programmer ti specify

On some systems is an int 32 bits or 64 bits (or even 16 bits on older

defined in the C standard.

When signed and unsigned values (variables or literals) of the same size
are combined the compiler assumes that all of the values are signed.
This can yield a problem if the unsigned integer is large enough that
the most significant bit is set because this bit indicates sign.
