Independent of what the standard says, some systems don't have dynamic 
memory management, and don't want it. 

If you don't have "free" on your system, you probably do not want 
"delete" either, depsite the fact that C++ requires "delete" and C does 
not require "free".

Certainly, if you don't have "free" there's no obvious portable 
implementation of "delete".
