That was exactly what I was looking for. Mystery solved, thanks!

I have a need to compare the addresses of two packets. Attempting to 
use the binary comparison operator, ==, on the packet info's address 
field fails miserably with "error: invalid operands to binary == (have 
‘address’ and ‘address’)". Is there a relatively pain-free way to 
perform such a comparison?
    
Include epan/address.h if you haven't already and use the macro 
ADDRESSES_EQUAL(addr1, addr2), which will "return true if they are equal 
and false otherwise."  This is assuming you're using the "address" type 
of variable to hold the addresses.
