I got the answer again and it seems that James is right and the
distributed executables have no restrictions on code size.
As I run the Upgrader.exe to update the default starter
version (16k) to the student version (64k), it seems that he is right,
I can see that the library files are updated.
I tested his patch and configuration and it works.
So if some hackers can port newlib over to PIC32, it is actually possible
to lift the code size limit.
