While porting some code I got the warning,

> warning: class `foo' only defines private constructors and
> has no friends

which gave me a scare until I realized the class *did* have a
static member function which called "new foo" using the private
constructor.  In fact, I notice the warning even appears if I
put the function body using "new" right there in the class
definition!

This warning should probably be suppressed when there are
any public static member functions in the class.

A sample file:

--------
class foo {
  int x;
  foo(int y) { x = y; }
public:
  static foo *make(int a) { return new foo(a); }
};
--------

As far as I know, there is no way to get gcc to suppress this
warning, short of using "-w" to suppress all warnings.  It
would be nice if there were a way to suppress specific warnings,
e.g., a #pragma or special comment that would suppress all
warnings on the following line, or a command-line option that
would suppress all warning messages whose text contains a given
string.
