This is the first I've heard of FineLine. I just gave it a try, and see that it's having trouble with these:

@ __CONFIG _CONFIG1H, _OSC_ECIO6_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
@ __CONFIG _CONFIG2L, _PWRT_OFF_2L & _BOREN_ON_2L & _BORV_1_2L
@ __CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
@ __CONFIG _CONFIG3H, _CCP2MX_PORTC_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_ON_3H
@ __CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L

How do you deal with these? Must the .INC fine be modified instead?

Is there documentation available for FineLine?
