  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.
	(Aren't there a few such ?)
