There is a forum discussion, where we discussed the PIC18F97J60 configuration mismatch.
https://sourceforge.net/p/sdcc/discussion/1865/thread/8142c22b/?limit=25#2a40
Needs to check the headers which are generated from .INC files from microchip.
Now for PIC18F97J60 looks like this:
name 18f97j60
using 18f67j10
ramsize 4096
configword 0x01FFFC 0xF8 0xF8
configword 0x01FFFD 0x07 0xF7
