import core.sys.windows.windows;

void main()
{
   FARPROC addr1, addr2;
   auto ptr = VirtualAlloc(null, addr2-addr1, 0x00001000, 0x40);
}

I just discovered while reducing it what the error message means: 
FARPROC is not void* like I thought, but (int function()), so it 
can't be used like I tried to do above. The compiler message was 
a little cryptic, but obvious in hindsight. Thanks!
