Your line
Fill_Screen_Z(8)
doesn't have a semicolon
should be Fill_Screen_Z(8);

As for that warning, I don't don't much about C (as opposed to C++), but C
doesn't seem to like void function returns, or at least with main.  If you
meant to compile with C++ (I had this problem when I first got djgpp), name
your files .cpp instead of .c, and compile with gxx.
