Bug fixes (was: "Recursion, need more stack space.")

According to Frank Heckenbach:

Fixed.

Fixed.

Indeed.

Probably.  However if you want to try yourself on that problem, look
into the GCC info documentation, and read about "machine descriptions".
There is something about how to describe each instruction a processor
has, and maybe it's a trivial error and somebody overlooked this
instruction.  Or else: Loading the memory reference into a register and
pushing that *might* be faster than a direct push (don't know).
