Follow-up Comment #3, bug #35407 (project avr-libc):

Thanks for the changes.

What will happen if a 16-bit SP target in avr2 resp. avr25 is compiled with
-mtiny-stack?

In that case the compiler assumes SP_H to be always zero. However, the startup
code will initialize SP to RAMEND so that SP_H is 1.

Shouln't SP be initialized to MIN (RAM_END, 0xff) for these devices?
