Er, what?  Each C file is compiled once.  The core files are compiled
and linked into pcb; the plugin's files are compiled once and linked
into the .so.  When PCB loads a plugin, the dynamic linker finishes
the link by resolving the plugin's references with symbols from the
pcb app.  The plugins have no core code in them.

Right.
