DMD-64 2.062 and GCC can't pass >8byte structs?

[E.S. Quinn]

Er, my apologies. The code on that post won't actually do what 
it's supposed to.  I wrote my testcode originally with very 
idiosyncratic variable names, and hadn't actually recompiled the 
code after I changed them for my post. This should actually work:

structc.c:
-------

#include <stdio.h>

struct passingstruct {
	unsigned int a;
	unsigned int b;
	int c;
};

void printatest (struct passingstruct value)
{
	printf ("hello!\n");
	printf ("%u %u %d\n", value.a, value.b, value.c);
}
----
structd.d:
------
import std.stdio;

struct passingstruct {
	uint a;
	uint b;
	int c;
	
	void printme () {
		writefln ("%d %d", a, b);
	}
}

int main (char[][] args)
{
	passingstruct test = passingstruct( 300, 200, 0);
	writefln ("%u %u %d", test.a, test.b, test.c);
	
	printatest (test);
	return 0;
}

extern (C)
{
	void printatest (passingstruct value);
}
