Not necessarily. But it can't be shared at runtime anymore, since

O.K. so we have to stress the term archive in your statement.

I am not talking specifically about PIC/non-PIC code here. PIC is
relevant because when you're doing dynamic loading you generally cannot

Practically you never do. But could, if you really wanted?
AFAIK you need PIC only to share libs in memory. The rest is already

Library archives (.a) and shared objects (.so) differ in several ways.

Aha! Grepping through /usr/portage/eclass/* for 'static' taught me something:
