There are (and always will be) some things that could be done. Here
are some I can think of:
sdcc -c -model-large -o large _atoi.c (where large
could be a different basename or a directory)
char KernelFunction3(char p) at 0x340;
If you can think of some more, please send them to the list.
<pending: And then of course a proper index-table>
