--- Comment #3 from Дилян Палаузов <dilyan.palauzov at aegee dot org> ---
Am I correct if I say, that the gcc plugin is backward compatible: the plugin
from the newest gcc can be used with any gcc but not vice versa?

How do nm and ar determine, if a plugin shall be used, for instance when `nm
test.o` is called?
