A perl script named inc2h.pl is available in the SDCC distribution that converts the
Microchip include files (assembly) into SDCC header files (C includes). You could do it
all by hand but the script makes it a lot easier.
The script can be found at <sdcc-source-directory>/support/scripts/inc2h.pl.
Running it as follows ...
$ cd <sdcc-source-directory>
$ perl support/scripts/inc2h.pl --help
... will provide the following information:
inc2h.pl - A utility to convert MPASM include files to header files
suitable for the SDCC compiler.

SDCC is licensed under the GNU Public license (GPL) v2; see
http://www.gnu.org/copyleft/gpl.html See http://sdcc.sourceforge.net/
for the latest information on sdcc.
Usage: inc2h.pl options
where options include:
--processor=processor
-p=processor
The name of the processor (16f84, 16f877, etc.)
--basepath=path
-I=path
The path to the "header" directory. The default is
"/usr/share/gpasm/header".
The header file will be written to the standard output.
So, to generate a header file name p16f877.h from the p16f877.inc file located
in, say, /usr/share/gputils/header/, you would issue the following command:
$ perl support/scripts/inc2h.pl -p=16f877 -I=/usr/share/gputils/header > p16f877.h
The only caveat (that I know of) is that the script is unable to infer the memory map
of the processor from the "inc" file. It must be told of the memory map using a table
in the perl source. Currently, the memory maps are defined for the following devices:
16f84, 16f84a, 16f627, 16f628, 16f876, 16f877, 16f873, 16f874
If this isn't in the list of processors you are looking for, let me know and I'll try to
update the script.
Hope this helps!
