You need to use an explicit cast, like this:

    movedata(_my_ds(), (unsigned long)double_buffer, screen, 0, 320*200);

Randomly poking around your code is usually a bad way to solve problems.  
You need to understand the diagnostics printed by GCC, and then correct 
the problem it complains about, not make some random change in the code 
that makes the warning go away...
