Has anyone looked into integrating 80C85 support into SDCC?

I use the Z80 SDCC compiler and it's great. But I actually have a project that (http://sourceforge.net/projects/hawk800/) that is all written in assembler and I would love to be able to port it over to SDCC C.

And is there a direction that someone could point me if I chose to try to do this myself?

Thanks,

Mike
