gcc can be used for 8-bit machines, such as the AVR series of 
microcontrollers and the 68hc11 and family. It's also much closer to 
ANSI C compliance, and affords compatibility with C++.

A few hours. Mostly just porting the patches to the 3.1.1 version of 
gcc. However, the backend that was written is pretty basic, and doesn't 
support a lot of useful things, like PIC code or soft-registers (using 
the DP). To add that, the easiest route is to port the 68hc11 backend. 
However, it's really big and I have no idea where to start.
