tests/get-timezone.c doesn't compile for me.

#include <itdb.h>
was changed to
#include <gpod/itdb.h>

and

#include <itdb_device.h>
had to be deleted.

When I run the command:
gcc $(pkg-config --cflags --libs libgpod-1.0) -o tz ./get-timezone.c

I get:
./get-timezone.c:37:42: error: dereferencing pointer to incomplete type
