Believe it or not I already have a test for missing pins in the mapping
file! But I didn't see a warning for the 18f4550 .... curious!
Well, as it turns out pin_C4 and pin_C5 are not declared in the device
files (although PORT_RC4 and PORT_RC5 are declared). I see also the
reason for this: the pins for the 18Fs are declared from the
specifications of the LAT registers and these don't have bits 4 and 5.
There are no corresponding TRIS bits either: these pins are input only!
It looks like I have to change my script to generate the pins for the
18Fs from the PORT registers. Maybe there are more input-only pins
missing in the device files.

Shouldn't be a problem!
