I received several responses (next day; talk about results!!).  Here is one
that appears to be in agreement with most of them.  Thanks to all that
responded.

In MyObj.h, say

class MyObj {
private:
	static int numObjs;
	...
public:	MyObj();
	...
}

In MyObj.cc, say

#include "MyObj.h"

int MyObj::numObjs = 0;

MyObj::MyObj() {
	if (numObjs == 0) {
		// I am the first object
		...
	}
	else {
		// I am not the first
	}
	numObjs++;
}
