what a lack of imagination.

actually, no. there is *no* os. we are talking about 8-bit
microcontrollers with 2kb of ROM and 128 bytes (!) of RAM in the minimal

it's not really a different type of toolchain.
it's a normal x-build gcc with a (rather minimal) sysroot (typically
hard-wired into the executable).
one speciality is that after linking the executable there is a
post-processing step that produces a ROM image.
so basically, this thing would be a derivation of the Cpp module
(actually, plain C is "a tad" more appropriate), and add a new target
type AvrImage or something like that.
