final HANDLE INVALID_HANDLE_VALUE = cast(HANDLE)-1;
const DWORD INVALID_SET_FILE_POINTER = cast(DWORD)-1;
const DWORD INVALID_FILE_SIZE = cast(DWORD)0xFFFFFFFF;

Why is INVALID_HANDLE_VALUE not const like the others?

It means when you try to use it like..

class Foo
{
   HANDLE bar = INVALID_HANDLE_VALUE;
}

you get an error.

Isn't HANDLE aliased as a void*? I guess you can't have a const (void*). 
Just a guess.
