It should be possible to create necessary definitions for TARGETTING GCC to 16 bit processor, however HOSTING (that is, running GCC itself in such a processor) is extremely difficult, propably outright impossible. Meaning: You can use any decent 32-bit platform to run GCC, which generates output to your favourite microprocessor.
