Only when one wants to re-target gcc: because that is the way gcc sees its
target: (more or less) stack based.

That is exactly how it is done in Jal (and I assume in all other PIC
compilers). Not very difficult in itself, but hard to add to an existing
compiler that does not think that way. BTW in Jal recursion is not
possible, I don't known for other PIC compilers.
