cc-1171 cc: WARNING File = bridge.c, Line = 684 The indicated expression has no effect. if (port == 0) port == DPORT; ^ Blech! Well, DPORT is by default set to 0. See the documentation of the define in the sources... This one will stay. I saw your second message about putting this in a conditional, but out of curiosity, why wouldn't you want to fix it? You don't have an assignment statement here, so if you do define DPORT, it won't take effect the way you want with the code like this. --Marc
