Overloading operator new() does not seem to work properly.
Here is an example from ARM, pp 282:

1 klamer@mi7 12:58 77> cat new.cc
// Get size_t by including stdlib.h
#include        <stdlib.h>

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

// Y*   p1 = new Y;
Y*      p2 = new(7) Y;

This did compile fine using Sun C++ 2.1 (== cfront 2.1)

Using g++ 2.2.1 results in:

0 klamer@mi7 12:58 78> gcc -v -c new.cc

new.cc:11: parse error before `7'

So a parse error is given on legal (IMHO) code.
