From Owen Kirby via bug 3431:

The attached patch file adds dissectors for the ZigBee protocol stack, 
which runs atop the IEEE 802.15.4 dissector. Also included is the
dissector for the ZigBee Encapsulation Protocol (packet-zep.c), used by
the Exegin Q51 protocol analyzer.

From me:

Fix a bunch of gcc (the compiler, not me) warnings.
