Microchip has tried to make it clear that the linker scripts are
"suggestions" rather than rules.  Most people will need to modify
the linker scripts for their particular application.  There are
some examples in the MPASM/MPLINK User's Guide.  If you do not
have a simple GOTO for your ISR at 0004, then you'll need to
increase the size of that section.
