I was able to make things work by changing something in windows.h.
I changed the parameter name in the FillMemory from "Fill" to "fill" and it worked:

Code:
VOID WINAPI FillMemory(long Destination,DWORD Length,char fill);


With the above line this compiles now:

Code:
#include <default.c>
#include <litec.h>
#include <com.h>

function run()
{
	
}
