Ick... Really, we can't store infinity in the trailer. But I didn't
reallize, that allowed length is so small (looking to nowadays data).
Sorry, I'm not gzip expert :-/

Yes, it is. maybe_warn() sets exit_value to 1 and this affects on all
calling programs (including hubertf's g4u, where I've detect this
behaviour first).

IMHO, we should change maybe_warn() with just warn() for this and fix
a message about reported sizes.
