Although the tiny does not have any ram as such, the registers are
addressable as ram entries (this applies to all the AVRs - it could be used
for optomisations of code in which the address of local variables are taken,
but it might lead to madness for the avr-gcc developers).  It would be
perfectly possible to dedicate a group of registers to be the "stack", and
use normal gcc to generate the code - that is pretty much what ImageCraft's
tiny avr-icc does.
