I have the following behaviour, which looks erroneous:

-------------file: problem.cpp-----------------
#include <cstdlib>
#include <new>
using namespace std;

void no_memory () {
    exit (1);
}

int main () {
    std::set_new_handler(no_memory);
    return 0;
}
--------------------------

Here's the problem: if the std:: prefix on set_new_handler is removed we get a
compile error:

       set_new_handler(no_memory);
                                 ^
       problem.cpp(16) : Error: ambiguous reference to symbol
       Had: set_new_handler(void (*C func)())
       and: std::set_new_handler(void (*C func)())
       --- errorlevel 1

If std:: is restored, it compiles and runs with no problem.  It would seem
that the 'using namespace std' should obviate the need for the std prefix.
This is DMC v852.


Thanks for any clarification,
