A key piece of information!

I appreciate that you let me know this!

So at the end of the day my only choice is to
go with the non extended instructions set and
make the diolan bootloader work with that and
thus Raphael's kind offer to look into adding
extended instruction set to SDCC is moot.

Raphael, if you agree with that, don't waste
time to investigate that, the above linked
to thread seems to indicate that it is pretty
pointless anyway: makes code generation harder,
does not improve performance (don't know if
that is true) and no-one using C is using (or
will be using it in the future as there are
no compilers that support it in the future).

Now back to debugging why my bootloader
does not work...
