you create a new header file called something like "processor.inc" which
has the text "#include <P18f455.inc>" automatically using a makefile
target. Generate this file every time using the forced make target
concept of your Make program. Include the "processor.inc" in all your
assembly files instead.
So when you change a processor, your makefile will generate a new
processor.inc and will re-compile all the code.
I can of course specify the header as a symbol defined

If you're using a Makefile you do not need to specify it twice. The
makefile can track all variables and you can just pass the variable
again as a define option for the gpasm commandline.
