I went back and did a diff on my sources and realized that mine is derived from
the Hitech-C port found at http://www.microchipc.com/sourcecode/ , not the one
linked to in this thread. I am pretty sure the only things I changed was some
#includes and the definition of #define rom in the system/typedefs.h file and
change the slashes in all the #include directives in all files. There was also
some bracketing issues in the static declarations of the descriptors in
autofiles/autodsc.c.
If there were any other changes, I think they were pretty trivial. Like I said
though, I haven't had a chance to test it yet. My whole reason for working on
this is because I want to create a single chip low-voltage ICSP that uses USB
for those other Mac users (an others) who don't have a serial or parallel port.
You could put a charge pump on the board and do non-lowvoltage too, using only
the power supplied by the USB bus.
I actually was able to get this to compile for 18f2450/2455/2550/2555 also.
