That's correct, and current AT&T SGS (SVR3 3B2, for example) appears to be
based on QCC.  I've been told that QCC and RCC are essentially the same
sources, with only the multiple register classes of RCC handled differently.
Your best bet would be to get the absolutely latest AT&T SGS you can and
proceed from there.  You might also consider working with Green Hills or
HCR or some other popular compiler vendor; why is it so important to have
the AT&T RCC product?
