gcc is much more permissive with system libraries than with regular
headers. -isystem PATHFOO makes gcc treat headers found in PATHFOO
as system headers. Doesn't gcc ignore this warning on declarations
coming from system headers? It's actually the opposite that happens:
bugs in system headers are more masked than non-system headers'.
