The operator new can still not be overloaded in the way ARM specifies (IMHO).
Allocating a class instance with a constructor with arguments results in a
parse error.

The code is:

// Get size_t by including stdlib.h
#include	<stdlib.h>

class Y {
	// ...
public:
	void *operator new(size_t size, int flag);
	Y();
	Y(const char *);
};

Y*	p1 = new(7) Y;
Y*	p2 = new(7) Y("This should be OK");

And the compiler fails on the line with "This should be OK" with the following
diagnostic:

Sun C++ does allow the code above. g++ 2.2.1 does if the new{7} is used
instead of new(7). (And so does g++ 2.3.1, but with warnings at -Wall).
