You will need to convert the "official" Microchip .inc files to .h 
files. This process is described in the installation instructions.

Please note that the 14-bit PIC support in SDCC is likely to cause you a 
few headaches down the road, as there are a few known bugs that require 
quite significant work on the 14-bit backend. If you want to use SDCC, 
the 16-bit PIC family is a better supported choice. If you want to use 
the 14-bit PIC family, I would recommend either JAL, assembler, or a 
commercial C compiler (some have a free version, subject to 
restrictions).
