Description

Deep down pn_messenger_recv() issues a poll() with a specific timeout. On ARM9 the poll timeout is reset to 0 because d->wakeup is always older than now. The reason is, that the time stamp is passed around earlier and one of the functions has a time_t instead of a pn_timestamp_t in the declaration.

Patch that fixes the problem is attached.
