The gnu C++ compiler doesn't like the following program, yet so far as
I recall, it works fine on C++2.0 from AT&T. Anyone know what's going
wrong? It reports "parse error just before malloc" on the line with the
second call to new. Seemingly, g++ doesn't support additional arguments
to new.	-- Andrew

#include "new.h"

extern "C" void *malloc(size_t);

class A {
public:
    void *operator new(size_t s) { return malloc(s); }
    void *operator new(size_t s, void *x) { return x; }
    int b;
};

main()
{
    A* a = new A;
    A* a2 = new(malloc(sizeof(A))) A;
}
