There is another option now, the VBCC compiler port to 6502 http://www.compilers.de/vbcc.html see the announcement: viewtopic.php?f=2&t=6100

Unsurprisingly. the OP’s C-compiler project didn’t progress beyond the discussion phase. Saying that isn’t a slight; it is meant to point out that developing a C compiler for the eight-bit 6502 family is no trivial undertaking—in fact, it’s downright difficult.

At this point in time, the vbcc compiler is, in my opinion, the best route to take if wanting to do C-development on the 6502. Dr. Volker has also developed a 65C815 C-compiler that appears to be well-designed.
