I suspect this is very naive, but I looked all through the on-line manuals and 
found no answer to the subject question.  The symbol table seems to be made
by the -g option to cc.  So what does -DDEBUG buy me?

One answer MIGHT be (I am guessing) the ability to denote some lines in my 
C code (with 'DEBUG'?), such as my favorite printf statements, so that they 
are compiled when -DDEBUG is declared, but not when it is not.
