Yes it does.

I guess this is related to the way the library works internally (which
I did not understand yet ;).
If it works the same for 16f877, you get 6 analog pins, while you
request 5. So one pin won't work in digital mode as one would
expect...
Maybe it requires a statement like:
if (ADC_NVREF == 0) then
if (ADC_NCHANNEL == 0) then
ADCON1_VALUE = 0x0
elseif (ADC_NCHANNEL == 1)
ADCON1_VALUE = 0xE
and so on...
Much code - a value for each line in the table - but resolved
compiletime when both are constants...
