I want to call Windows api function VirtualAlloc. I include 
std.c.windows.windows but get the following error from dmd 2.061 
(and 2.060):

Error: no size for type nothrow extern (Windows) int()

What does this message mean? If I provide my own prototype of the 
function, same error.

Can you give a self-contained repro that illustrates the problem?

Also, please use core.sys.windows.windows instead. The std.c.* package 
is going to be deprecated soon-ish.

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!
