I had a look at the docs I have for "ld" 
and there is a pretty terse
mention of the "garbage collect sections" 
switch.

Where does one find fuller do***entation on "ld" 
(and other GNU utils)? Do people just get the source 
code and study it?

My guess is that this might remove entire 
sections if there is no reference to symbols 
in them, and would thus require that each 
procedure reside in its own named section (?).
That does not seem to be the C practice to 
have so many named sections. I've been a bit
nervous that I have each module in a different
section now. There might be some bad side effects
of having hundreds (or thousands) of sections for
"ld" in a big program. (?)
