The use of '__memx' - how can i resolve code issue? The changelog you quote mentions __memx only w.r.t. static initialisers, not named address spaces in general.
In reality, named address spaces like __memx were added to GCC...

ATTiny85 and the Reset pin
You could actually manage this with the normal reset functionality of the pin intact. Place the button on the reset pin thus:
This would allow you to use the...

For HVPP, I might agree. But HVSP is easy enough to manage, even in circuit. It only takes one more pin beyond what ISP...

If you program RSTDISBL, you'll need an HVSP-capable programmer to re-program your t85.
