Thank you Sebastien, Then is weird, using previous libs and the following code, I was able to set A4 as analog input (a 10k potmeter) and A0 as digital output, making a LED to blink in 0 - 1023 (adc returned values) miliseconds interval. Note that first, all are digital and then from A0 to A4 are analog... I was able to use the same code on SDCC... It is possible to use an analog input as digital output? ADCON1 is set accordingly but TRIS is set as output for A0... this let me use any analog input as digital output? I made the tests few times (even now, my led is blinking on breadboard)
