I used my new footprint as suggested by you and use it in connection
with gschem and gsch2pcb.

After placing the new footprint on the layout and load the netlist, I
only see two ratlines going to the first 2 pins. The last pin is not
connected. If I try to route a copper wire to it, I get a short circuit.

With mouse over, the third pin give:

Element name: C105
Pin Name C105-3      !!!
Netname --

Is this a problem with gsch2pcb?

I used this as m4 footprint not in the .fp style.

Klaus
