Well, datasheets is one thing, GCC's internal notion is yet another. > Or do you want GCC to print out how much RAM each device has? No, I would expect GCC to print its rationale for this rejection. e.g. something like "allocating 2050 byte of stack exceeds maximum stack size (1024 bytes) ..." > > Well, my view is different: The avr's default set of multilib variants is > > non-suitable as general default set of multlib variants.

We will see, I am currently looking into implementing custom multilibs for avr-RTEMS, which may result into a patch addressing this as a side-effect. However, the avr's multilib implementation diverges from what is used almost elsewhere in GCC to an extend, this is a tedious.
