Re: power_out - pin_bidi warning

All right, I've reduced this matter to 3 warnings. In a 4-layer pcb
with a microprocessor with 176 pins it's not a bad thing.
Nevertheless, putting a Power Flag just toggles the warning from "pin
power_in not driven" to "pin power_out connected to pin_bidi". This
doesn't affect the pcb layout so if no one has a better idea, I'll be
working with this warnings in the schematics.
Thanks for your help,
