A call to strcat with NULL as the second argument core dumps with a memory 
fault on Ultrix.  Why would anyone want to do this anyway ? How about....

	strcat(foo,getenv("FOO"))

		instead of

	if (getenv("FOO")) strcat(foo,getenv("FOO"));

Actually, just coding strcat(foo,NULL) will dump.  Anyone run into this ?
Am I doing a no-no here.
