I'm using the GCC-68hc11 here in school for my microprocessor interfacing
subject. I've no idea how "good" it is because so far we've been doing
fairly simple stuff (i.e. blink-the-LED) and my hardware has 8K (!!) of
memory. Having to support the overhead of GCC is sucky though, the
compiler has to use memory as registers.. and the 68hc11 is "easier"  to
port to than the 8051 for example because it has two or three 16-bit
registers that can hold the result of a multiply..
