Which is the correct location for the poll.h header? We have both ffserver.c:#include <poll.h> libavdevice/dv1394.c:#include <sys/poll.h> but configure only checks for poll.h, not sys/poll.h. On my glibc-based system poll.h just contains #include <sys/poll.h>. OK to change poll.h to sys/poll.h then? Diego
