Are there any known problems with g++ 2.2.2's handling of the new operator
when it is given an explicit placement option?  While trying to understand
a problem g++ was having with the output of a code generator, I tried
it on the following trivial example of explicit placement, simplified
from Stanley Lippman's "C++ Primer, Second Edition": 

    // example of placement argument to new, taken from Lippmann, "C++ Primer".

    #include <iostream.h>
    #include <new.h>

    class Foo {
    public:
	int val;
	Foo() {val = 0;}
    };

    char *buf = new char[sizeof(Foo)];

    main() {
	Foo *pb = new ((void *)buf) Foo;

	// check that objects were placed in buf.
	if ( (char*)pb == buf)
	    cout << "Operator new worked!: pb: " << pb << " buf: " << (void*)buf << endl;

	return 0;
    }

This works with our copy of AT&T C++ 3.0, but g++ gets a syntax error:

    g++ -v -o new new.c

      new.c: In function `int  main ()':

I am doing something dumb?  Is there a workaround?

Thanks.
