Alberto,
Since SDCC is open-sourced, making it do whatever we want is just a matter
of writing code. That's the beauty of having the source. The beast though,
is you have to write the code...
There are at least two ways we can approach this:
1) add a command line option --with-bootloader that will tell SDCC to use
a jump to the start of main.
2) add a #pragma.
As far as the mechanics of adding the jump, well that's trivial.
